X and 2.6.5 kernel: update of 2.6.5 kernel locks my laptop

[slaven peles <peles@bellsouth.net>]

Hi,

After updating kernel 2.6.5-1-686 from version 2.6.5-2 to 2.6.5-3, my laptop 
gets locked as soon as X is started upon boot. I get just a blank screen, 
keyboard does not respond, and all I can do is to turn the power off. It 
really sounds like it has nothing to do with X, but in /var/log/messages it 
says this is a XFree86 bug.

I have Radeon M9 card, and I'm running up to date sid. Please let me know if 
this is a known problem and if there is a workaround. Or, should I inquire 
further on debian-kernel list? Also, let me know if I should supply some 
additional information.

Thanks,
