Avoiding the interrupt sharing is still useful, since you avoid the
I/O read from the interrupt routine. So that can have an effect.

That was the primary driver for the MSI support I've added.
Unfortunately MSI-X didn't work out, so it's still disabled - so for
the re0 it still falls back to INTx. I'd like to get back to getting
MSI-X working.

Matthias, can you check if disabling sdhc* and ichsmb* does anything?
