[ale] PCI kernel drivers and IO remapping



So short of a new driver that works on the new kernel, you'll need to keep
the old kernel. I've seen older scientific hardware hidden behind layers of
firewalls just because an upgrade would ruin it's ability to use a multi-$K
data capture card.

Welcome to the club!

you did recompile that module for the new kernel?
