[ale] interrupts in linux??

[Geoffrey]

Generally, if the device drivers are loaded via a module, you pass it as 
an arg to the module (irq=7).  If it's built into the kernel, you pass 
it to the kernel on the boot command line, or add it to the boot loader 
(lilo,grub) config file.  For lilo, you use the 'append' arg.  I don't 
know about grub.  I can manipulate some irq assignment via the bios as 
well, but that's always looked a lot like black magic, mirrors and blue 
smoke to me...
