You cant do gigabit with a 32-bit card unless you have a lot of buffer space, 
which the netgear doesnt.  IF you have no other cards in the box OR  you have 
a dual-bus system with ONLY the gig card on one bus, you might squeeze 
through. 32bit PCI cant do sustained 1 Gb/s transfers, so your longer packets 
will have problems making it through. Its simply not suitable. Its like doing 
100BT on ISA. 

If you have a hard drive on the same bus you have no chance.
