Serial port IRQ strangeness

I have a Debian 1.1 machine with 4 serial ports, each on its own IRQ.
I edited /etc/rc.boot/0setserial to configure the appropriate IRQs.

Question #1:  At boot, when /etc/rc.boot/0setserial runs, it complains
"no such device" for each of the devices.  If I do the setserial as 
/etc/rc2.d/S14setserial (after ), it works.  Why?

Question #2:  I am running diald.  Periodically, the following messages
appear in /var/log/messages:

kernel: Serial driver version 4.13 with no serial options enabled
kernel: tty00 at 0x03f8 (irq = 4) is a 16550A
kernel: tty01 at 0x02f8 (irq = 3) is a 16550A
kernel: tty02 at 0x03e8 (irq = 4) is a 16550A
kernel: tty03 at 0x02e8 (irq = 3) is a 16550A

and the IRQs for cua2 and cua3 are changed from 2 and 5 back to 4 and
3!  Any ideas?
