I don't know if it's because of "agpmode=-1", or because of some other reason
(although I don't think I changed anything): now I can't even load the radeon
module without crashing the system (completely). This is what I captured on my
notebook, when I was logged in to the mac mini via ssh and tried a "modprobe
radeon" from there:

...that's when the system freezes.

Maybe I'd be better off without the microcode?

Alex, from what I remember you are the main developer of the radeon module?
Would you be interested in more debug information?

By the way: radeon now works very well on my AMD64 notebook (with an R300
chipset). For the first time in maybe two years I can now properly use Google
Earth on that system - and it's the first time this works with a completely
free driver (Ubuntu 11.04, KMS). Thanks for the good work!
