Usually there is not need for the whole sequence, just Alt-SysRq-R, which 
takes the keyboard away from X. You can then switch to a text console with 
Ctrl-Alt-F1.
However: Sometimes (well, most of the times during my last ATI struggles) 
the screen was still blank. But I could reboot with Ctrl-Alt-Del. And 
sometimes the system was so frozen even the SysRq trick did not help. But in 
cases when only HAL does not work and recognize the keyboard, Alt-SysRQ-R 
should work just fine.

I know how you feel, I also had huge problems with that. And then, all of a 
sudden, with the new 2.6.31-tuxonice kernel, everything was fine and 
working.
