BTW, I had a look at the radeon card's resume code at 0xc000:3 and attempted to implement it in a kernel module. The code is pretty simple, but it's quite long. My module isn't finished, it only turns off the display and resets the memory. I had to stop because I've a lot of things to do for school now.
Ole Rohne meant that the code is potentially dangerous because it pokes around with undocumented PLL registers, so I will not send it to the list: I will send it only to those who explicitly ask for it.
