I am sorry -- my initial testing weren't throurough enough. Now, booting
to single-user, without any drivers loaded, i can reproduce the bug:

modprobe agpart # loads fine, AMD 761 chipset found
ulimit -c unlimited # only occurs if core file sizes are written
./testgart &
pkill -ABRT testgart # before testgart ends

testgart AND pkill process hang. Nothing will kill them. "pkill pkill"
hangs too :)

Testgart is the one by Jeff Hartman.

Doesn't seem to be NVIDIA drivers causing this. Note, with ulimit -c 0,
testgart terminates, printing "Aborted".
