That will prevent the driver from loading -- the io=.. and irq=.. parameters
are only valid for ISA drivers.  The PCI drivers can reliably detect the
card and read the IRQ line from a PCI configuration register provided for
this purpose.

This can be various problems, although most of them won't be fixed by
switching card types.

You must use v0.99H or later with most 3c905B cards.  The v0.99E driver will
not work.
Read the detection message.  An override to "100baseTx" will not work.
