Hi,
I just tried booting the new 2.6.10 kernel with the
radeon DRM module from CVS (at dri.freedesktop.org),
and the IRQ was left unrouted at IRQ 11:
[drm] Initialized radeon 1.13.0 20041207 on minor 0:
ATI Technologies Inc RV280 [Radeon 9200]
ACPI: PCI interrupt 0000:01:00.0[A] -> GSI 16 (level,
low) -> IRQ 16
agpgart: Found an AGP 3.0 compliant device at
0000:00:00.0.
agpgart: X passes broken AGP3 flags (1f00420f). Fixed.
agpgart: Putting AGP V3 device at 0000:00:00.0 into 8x
mode

Disabling IRQ #16
Adding the "pci=routeirq" option fixed things. The
relevant lspci output is:

I am sending you this email as requested by the dmesg
output.
