Are you sure this is no hardware problem? You could build a custom kernel
without "hme* at sbus? ..." and see if that boots.

I suppose there is a PCI bus attachment missing for the qfe; pci versions
of hme work in general, this is from my U5:

hme0 at pci2 dev 1 function 1: Sun Happy Meal Ethernet, rev. 1
hme0: interrupting at ivec 3021
hme0: Ethernet address 08:00:20:99:fc:91
nsphy0 at hme0 phy 1: DP83840 10/100 media interface, rev. 1

With a little experimentation and dmesg output from you it should be easy
to add the missing glue.

Well, I have a sbus qfe in my sparc LX, it attaches as hme0 through hme3
and works just fine. So this should just work (tm).
