 Yes, with your attached patch, on a CURRENT kernel, the soundcard
 produces audio when it is configured to use IRQ 5.  However, as
 previously mentioned, when fxp0 is also on IRQ 5 the machine locks up
 when assigning an IP.
 
 Now, I've also booted a 2.6.22 linux kernel (although one for use during
 system installation, but with ACPI nonetheless), which is known to work
 on this machine to see what the IRQ assignment is on such a kernel.
 I've attached part of the dmesg output that kernel generated.
