> Is there actual support for the ide controller in the multia? [and axppci33?]

No, although the hardware is almost identical to other systems where
we DO support IDE.

Unfortunately, every platform routes interrupts differently, and
although the multia and axppci33 use the same sio ("Intel 82378ZB
System I/O") as the eb164 systype, the interrupt isn't established
with special-case code on the lca systems like it is on the eb164.
(See chipset tag pc_pciide_compat_intr_establish if you want to
work on it!)
