The 3ccfe575 is actually a completely new design, based on the 3Com Cyclone
core instead of the older Boomerang core. It's *not at all* the same card!

But I'll bet you are not getting more than one interrupt (as reported by
/proc/interrupts)..
What changed? The 3ccfe575 implementes new brain-damage from the
PCMCIA committee. Despite the fact that PCI handles shared interrupt just
fine, the committee felt that an new register was needed to clear the
card's latched interrupt, and this new register is in an additional (!)
address space.
So after the interrupt is handled normally, using code common to the PCI
version, the v0.99G driver clears this additional register. (And yes, there
is a race condition here..)

This is unrelated: the LED state is inverted by default (?!).
The driver can set bit 4 (0x0010) in the 'ResetOptions' to reverse the
state. This is clearly a hack, since the most of the ResetOptions bits are
read-only, and the manual still lists bits 4-7 as "reserved".
Look for this change in v0.99H.
