[ale] Changing an IRQ ?



My serial irq's only show up when the port is in use.  For example, with
my network up on my modem I see:

 0:    3558933   timer
 1:       2859   keyboard
 2:          0   cascade
 3:      32228 + serial		<<-------------------------
 5:          1   sound blaster
10:       9328   eth0
12:     148875   PS/2 Mouse
13:          1   math error
14:      16552 + ide0
15:         12 + ide1

But when it's down I see:

 0:    3558933   timer
 1:       2859   keyboard
 2:          0   cascade
 5:          1   sound blaster
10:       9328   eth0
12:     148875   PS/2 Mouse
13:          1   math error
14:      16552 + ide0
15:         12 + ide1

I assume it's this way so the irq's may be shared, as often is the case
when you have more than two serial ports.
