Yep, nothing else seems to be jerking around, though I have not done
anything seriously stressful yet, just basic desktop stuff.

Should be the same exact chip if I remember the 4400 motherboard right,
just a different version. It's a Mach264 GT according to the chip label I
think. Mine has 6 MB of VRAM.

Thats odd, how is primary device 00:12:0 and the card at 0:18:0? I can
post the full XFree log and config somewhere if you want it.

Yes, it hangs with no usb devices connected at all after waiting for SCSI
devices to settle.

Also, what are the serial TTY's supposed to be called? When I fire up the
dec 13th kernel, I can't log into tty00, it says root login not allowed on
this console even though it's set to secure. If I turn it off and add
ttyZ0, it works, but only if I'm on a serial console. If I boot graphical
head, getty never starts and shows up on the serial line. Same kernel,
weird.
