Public bug reported: I have a dual monitor set-up using two separate single head video cards (r128 and mga). Worked fine in Hardy, but upgrading to Intrepid left Xorg at full CPU usage when starting up. It hangs in module libint10 while "booting" the second video card.
Bug seems to be introduced with Xorg 7.4. Downgrading Xorg to 7.3 (xorg- server 1.4) is not a very clean solution but works for me until this bug is fixed or until I get new hardware. (I also had to blacklist the kernel module evdev because some keyboard keys were doing weird things because of the downgrade.) My preliminary analysis: the PCI bus scanning/accessing code is replaced with libpciaccess in 7.4 [1], but not all video drivers are yet ported [2]. Normally not a problem, unless you try to boot a secondary card with it. Until ported drivers are being published, this will stay a problem I think.
