Subject[OOPS] pegasus + MediaGX: Oops in khubd, the continuing story?

I got fed up with all those Oops'es, so I started scribbling one on a piece of
paper. This is what ksymoops makes of it:

ksymoops 2.4.1 on i586 2.4.4. Options used
-V (default)

-o /lib/modules/2.4.3 (specified)
-m /boot/ (specified)

3 warnings issued. Results may not be reliable.

I may have made some transcription errors, but the main stuff is there.

This Oops (and others just like it) appear when the pegasus module is reloaded
into the system. Some info on the system and the circumstances:

MediaGXLV (200 MHz) + 5530 'kahlua' companion chip
(so this is ohci usb)
60 MB RAM (+4MB for video)

SMC 2202 (pegasus chip) 10/100tx USB NIC on a 10baseT LAN

Oops also appears on 2.4.4
