I beg to differ with you.  Here's my interrupts:

linux:/proc$ cat interrupts
 0:   19164367   timer
 1:      23488   keyboard
 2:          0   cascade
 3:      27884 + serial
 4:     338984 + serial
 9:      13305   eth0
10:     131353 + serial
11:         33 + aha152x
13:          0   math error
14:     312959 + ide0
15:        894 + ide1

Irq 2 is clearly the cascade, and irq 9 is a valid irq.  My understanding
was to avoid using 2, as 9-15 are linked through it. 

Also the cua devices are depreciated, you should use the ttyS? instead of
cua?.
