Whenever I log out of KDE, IRQ 11 is disabled on X server restart (kdm restarts it). It always results with the dmesg below and sometimes the new X loses keyboard input (ps2 keyboard, usb mouse). USB mouse works well. X works (sans keyboard sometimes). Network is dead. irq 11: nobody cared!

ATI rage128 graphics with DRI enabled; I get the following dmesg lines on X server start and at least the agpgart lines on each X server restart too. I have seen this bug some time earlier too, probably in 2.6.11 timeframe, or in early 2.6.12 timeframe.
