bge(4) failure, Dell 12G hardware, BCM5720C

[Sean Bruno]

Trying some hackery today in my netboot environment with the Dell 12G
R620.  I had to disable some bios calls in bios.c after reviewing an
email from Doug Ambrisko, and I see a pretty hard failure of bge(4) on
stable/7 with yahoo modifications on i386.

I've tried disabling msi via:
==== //depot/yahoo/ybsd_7/src/sys/dev/bge/if_bge.c#49
- /home/seanbru/ybsd_7/src/sys/dev/bge/if_bge.c ====
5633c5633
<       sc->bge_msi = 1;
---
>       sc->bge_msi = 0;

This quieted a lot of errors but the interface still appears to be non
functional.

P.S.  Not related to the bge(4) failure but might be interesting to
others who are trying to get the Dell 12G h/w working in their
environment:
