Panic with BCM5751 NIC

My computer at work was recently upgraded to an HP dc7100 with integrated 
Broadcom BCM5751 Gigabit NIC. Using Joerg's patch posted to this list (see 
below) I am able to get my NIC detected, but whenever I do this, either in 
the kenel or loading the module I receive a kernel panic.   Just before the 
panic is a message reading:  "RAM parity error, likely hardware error"

And then that panic is: 

Fatal trap 19:  non-maskable interrupt trap while in kernel mode
Stopped at cpu_initclocks t0x6e: inb $0x84, %al

This is, of course, transcribed by hand.  I have been unable to get any debug 
information out of the dump, even though I have -g set in my config.  I am 
probably missing something else.  Note that this NIC works fine in FBSD 
6-CURRENT, which is where I am sending this from.  Any thoughts or 

Here is the patch Joerg supplied a few weeks ago:
