Is this a 3c59x bus_master prob? urgent!

Hi folks,
I've been having problems with a 3c905 card (original, not B or C) in that sometimes I cannot
ping the machine. After some hours it will respond again. It _may_ coincide with network load
(NOT on that machine which has very low load, but on the network segment), as it usually
happens during the day and not in the evening, although neighbouring machines return good ping
times.
I set debugging to 6 and the messages "Host error" and "transmit timed out" (see bottom of
mail) appeared whenever the machine was non-responsive.
After reading resources on the Net, I assumed that this is a bus error. Old resources (for v 0.40)
suggested altering vp->full_bus_master=1 to 0 (line 956 in version .99H). I did this, recompiled and
the machine reboots OK, but I won't know until Monday (and the net gets busy again) whether this
is the correct solution.
I rely on the machine to promote my own web design company and host my customers' sites, so I
need to have it working ASAP. Unfortunately I can't afford a brand new machine, and I want to avoid
replacing the NIC as the hosting ISP is 5 hours drive away :-(.
