Yes, I work in the tech department and we service and repair our own machines. Thank you for that, they are under AppleCare and we will keep that in mind. Thank you!
They won't work on new MBP 2012 because hardware drivers are not supported!

Of course not, Snow Leopard nor Lion has drivers for the rMBP. This only will work on the Late 2011 Macbook Pro.
Does 10.6.8 run at full speed on these (late 2011) machines? Does the DisplayPort work (to drive a TB or 2560x1440 display)?
I only ask because I have successfully installed 10.6.8 on two July 2011 Mac mini servers (quad i7, HD3000). But it requires updating a number of additional kext files to get correct performance for the processor and the graphics.
Geekbench before these patches is approx 2000, and approx 8000 after applying the kexts. There is a VERY lengthy thread on this on the Apple forums.
Is the same true for the early and late 2011 MacBook Pros? Or does a basic 10.6.8 work fine?

Everything works.
Sorry Spectrum, I didn't think to do any before-and-after benchmarking. When I get some time I'll take a look at some of the published benchmarks for my Late 2011 MBP on Lion, then run the same ones myself on SL. You've got me curious now. Thanks for the nudge to check the forums on this.
I use this machine for editing HD videos in Adobe Premiere, and if there was a loss of performance when I downgraded I can't see it. File copies through the GigE run at a solid 600Mb/s to my Linux server. I've only used the Thunderbolt port up to 1920x1080, with DVI and HDMI adapters, but it worked as expected.
So it runs a 27" display OK? And would you be able to post your Geekbench score?
It sounds like it is probably working great, but I would be really pleased if you can post your Geekbench score under 10.6.8 - compared to the average Lion score.
Thanks!
32-bit Geekbench score for my Late-2011 13" MBP was 7128....
I think it's important to note this hardware first shipped with Snow Leopard (and a promised free upgrade to Lion). The gray 10.6.8 factory install disks could be ordered from Apple as late as March 2012.
Thanks for the info - I hadn't thought about using the Geekbench browser to look or 10.6.8 submissions.
One point though: I didn't think the "Late 2011" MacBook Pro ever shipped with 10.6.8 did it? (I know the "Early 2011" Macbook Pro did.) Surely Lion was already deployed in all hardware by October 2011?
I do not recommend, that you download your OS from a piracy site. It can contain some nasty surprises!...
Anyways, I tried it with the latest release of SL, and it crashed everywhere, kernel panics and I don't know what. Got kinda desperate, then I found this thread. So I downloaded the 10.6.7 ISO from this swedish pirate site, gave it another whirl, and next thing you know, boom shakalaka, the laptop was up and running again.
No. Snow Leopard will crash upon boot or be very unstable.
