Just one more note here. I tested hibernation/thaw cycles on one of my
old machines, an HP Pavilion ZE4201 notebook, which has integrated
Radeon graphics (IGP 340M, which is RS200 chip). This box is a 32-bit
machine, as opposed to my ThinkPad T510, which is running 64-bit stuff.
Similar behaviour on hibernate/thaw - with nomodeset, no trouble. With
KMS, trouble after a few hibernate/thaw cycles (NULL pointers and other
kernel dumps onto the console). Interesting. Maybe the problem is not
Intel specific after all.
