Apparently adding this to doesn't change much, except that ali5451 now uses
irq10 along with ati graphics chip, network card, wlan and usb.

The patch you supplied did not help me. I tried to find the place where it
fails. I applied attached patch to ali5451.c from 2.5.50 kernel. This is what
I get in dmesg now:
probe ...
creating ...
PCI: Found IRQ 10 for device 00:04.0
resouces allocation ...
resouces allocated.
snd_device_new is called.
chip initializing ...
pci_dev is NULL after pci_find_device!
ALSA sound/pci/ali5451/ali5451.c:2160: ali create: chip init error.
Hope this helps,
Rafal
