I don't know the exact nature of the bug, but compiling in the agp
driver on my laptop locks up the unit on resume.  Runing without agp
compiled in is fine.  The lockup isn't every time ... and it isn't
solved by suspending and resuming with the console active.  The
relavant probes are:

apm0: <APM BIOS> on motherboard
apm0: found APM BIOS v1.2, connected at v1.2
pcib0: <Host to PCI bridge> on motherboard
pci0: <PCI bus> on pcib0
agp0: <Intel 82815 (i815 GMCH) host to PCI bridge> mem 0xf4000000-0xf7ffffff at device 0.0 on pci0
pcib1: <Intel 82801BA/BAM (ICH2) PCI-PCI (AGP) bridge> at device 1.0 on pci0
pci1: <PCI bus> on pcib1
pci1: <ATI model 4d46 graphics accelerator> at 0.0 irq 9

then: 

info: [drm] Checking PCI vendor=32902, device=9283
info: [drm] Checking PCI vendor=4098, device=19782
drm0: <ATI Rage 128 Mobility MF (AGP 4x)> port 0x2000-0x20ff mem 0xf0000000-0xf0003fff,0xf8000000-0xfbffffff irq 9 at device 0.0 on pci1
info: [drm] AGP at 0xf4000000 64MB
info: [drm] Initialized r128 2.2.0 20010405 on minor 0
info: [drm] 8192 13 12

This laptop otherwise suspend/resumes fine (ie: without agp).

Dave.
