Seems that the new drm schema requires an interrupt to attach.

"dmesg" returns:

pcib0: <ACPI Host-PCI bridge> port 0xcf8-0xcff on acpi0
pci0: <ACPI PCI bus> on pcib0
agp0: <Intel 82443BX (440 BX) host to PCI bridge> on hostb0
pcib1: <PCI-PCI bridge> at device 1.0 on pci0
pci1: <PCI bus> on pcib1
vgapci0: <VGA-compatible display> port 0x9000-0x90ff mem
	0xd1000000-0xd1ffffff,0xd0100000-0xd0100fff at device 0.0
	on pci1
drm0: <3D Rage Pro AGP 1X/2X> on vgapci0
device_attach: drm0 attach returned 2
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

 .. which corresponds to ENOENT and "lspci -vvv" gives:

Didn't this used to work?
