Just to clarify. Do you mean you updated the Windows broadcom driver
which resolved the LUN reattachment issue, or did you update the PXE
rom to solve the 10MBit issue?
I think I've heard of Broadcom cards that wouldn't negotiate to
anything else besides 10MBit/s with their native PXE rom(not only in
combination with gPXE) and it would be interesting to know if this is
the case here. A new PXE rom from Broadcom could resolve this issue.

Thanks
Thomas
