BUG in 2.6.28.7, possibly yenta-related

[Eric Buddington]

Linux (none) 2.6.28.7 #1 Mon Feb 23 12:00:54 EST 2009 i686 unknown
On a PIII Armada M700 laptop

BUG occurred while running udevtrigger, which causes udevd to modprobe
a bunch.  Here's dmesg, showing the first two BUGs (I assume only the
first is really useful):

...agpgart-intel 0000:00:00.0: AGP aperture is 64M @ 0x50000000
