I am currently running Red Hat 5.1 with kernel version 2.0.35 and have downloaded and recompiled 3c59x.c.  The card works fine using Windows 95 on the same machine (Pentium 233 MMX).

Saw it today when I did an install.  In my cmos settings I set all my IRQs
to legacy devices w/ manual IRQs.  This caused the IRQ 255 problem for me. 
Setting the BIOS to handle the PNP IRQs solved the problem.  Someone else
would need to verfiy this but I'm willing to bet if your CMOS has an
option for PNP OS set to yes then you would get the same error.  Hope this
helps.
