bge0 watchdog timeout -- resetting on 8.2-PREREL never recovers

[Steven Hartland]

This may be totally unrelated to bge, investigating a potential failing stick
of ram in the machine in question so until we've ruled this out as the cause
don't want to waste anyone's time.

I did however notice the logic between the two fixes for DMA on 5704's on PCIX
in svn differ so wondering which ones correct:-
http://svn.freebsd.org/viewvc/base/head/sys/dev/bge/if_bge.c?r1=216085&r2=216970
http://svn.freebsd.org/viewvc/base/head/sys/dev/bge/if_bge.c?r1=217225&r2=217226

r216970 results in:
1, 0, BUS_SPACE_MAXADDR_32BIT, BUS_SPACE_MAXADDR, NULL,
where as r217226 results in:
1, BGE_DMA_BNDRY, BUS_SPACE_MAXADDR_32BIT, BUS_SPACE_MAXADDR, NULL,

    Regards
