pata_ali: troubles with interrupt

Hi,
I have a "hamlet xsataci" card[1], which is basically a PCI card with
both an Ali M5228 PATA controller and a M5281 SATA controller:

05:02.0 Mass storage controller: ALi Corporation ALi M5281 Serial ATA / RAID Host Controller (rev a4)
05:02.1 Mass storage controller: ALi Corporation M5228 ALi ATA/RAID Controller (rev c6)

I'm using kernel 2.6.19-rc6 (current git, pulled few hours ago) SMP
(dual core CPU) and PREEMP enabled; PCI_MULTITHREAD_PROBE is disabled.
alim15x3 works (almost) fine:

Uniform Multi-Platform E-IDE driver Revision: 7.00alpha2
ide: Assuming 33MHz system bus speed for PIO modes; override with idebus=xx
ALI15X3: IDE controller at PCI slot 0000:05:02.1

hdd: cache flushes not supported
hdd: hdd1 hdd2

only problem is that hdd supports UDMA66 but it's configured as UDMA33.

sata_uli handles the SATA part of the board fine (nothing connected ATM,
but I plan to use the external port).

pata_ali doesn't work for this board though:

I also tried booting without sata_uli but I still get the same screaming
interrupt.
Note that the card has only one PATA channel (and 2 SATA ports).
