This oops made me unable to use my 3Com CardBus NIC.

I've been able to pinpoint the culprit of this: it's the
"make-KOBJ_NAME-match-BUS_ID_SIZE.patch" patch that it's causing the
oops for me when booting 2.5.69.mm5.

Reverting this patch solves the oops for me.

I don't have the resources to investigate why this patch is causing the
oops for me, but I'm willing to help you, if you need it :-)

Thanks!
