[gPXE] Dell T300 w/Broadcom chip: gpxe hangs during dhcp

[Peter Scheie]

With sha0's help, I built gpxe with the undiebusy patch and his initrd patch. 
While this works on a VirtualBox VM with an Intel nic, when I run it on the Dell 
T300 (with the Broadcom nic) where this problem first appeared, it says it can't 
find any NICs.  Using the singleundi patch did work on this Dell (but I didn't 
have sha0's patch included in that version of gpxe, which I need).  Suggestions?
