I have a similar problem, so I'll wait before posting to see what 
suggestions others have for solutions to yours.
I've managed to hack my way around my problem by freeing up some low 
irqs -- disabling one of the com ports (irq 3) and the parallel port in 
the bios, and taking them out of my system configuration in a custom 
kernel.  I'm not sure I needed to get rid of the parallel port, but I'm 
not using it anyway.  It's a real hack, but doing so allowed my two 
NE2000 cards to be placed at irq 3 and 5, and then everything worked.
