freebsd stable - Feb 2004 - rndcontrol doesn't work on -STABLE?

Following instructions I found on the web to deal with rndc issues, I
tried to sent entropy by doing the following:

grep ahd /var/run/dmesg.boot
ahd0: <Adaptec AIC7902 Ultra320 SCSI adapter> port
0x4000-0x40ff,0x3800-0x38ff mem 0xfe9e0000-0xfe9e1fff irq 16 at device 7.0 on

da1 at ahd1 bus 0 target 1 lun 0
da5 at ahd1 bus 0 target 5 lun 0
da4 at ahd1 bus 0 target 4 lun 0
neptune# rndcontrol -s 17
rndcontrol: setting irq 17
rndcontrol: rndcontrol: Invalid argument

I'm quite limited in number of sources, as its a remote server, so nobody
on a keyboard or anything like that:

neptune# grep irq /var/run/dmesg.boot
IOAPIC #0 intpin 2 -> irq 0
IOAPIC #0 intpin 17 -> irq 2
IOAPIC #2 intpin 2 -> irq 16
IOAPIC #2 intpin 1 -> irq 17

pci0: <unknown card> (vendor=0x8086, dev=0x2483) at 31.3 irq 2
atkbd0: <AT Keyboard> flags 0x1 irq 1 on atkbdc0


I tried 18 for my ethernet as well ...

I found this comment in src/sys/i386/i386/mem.c:

        /*
         * XXX the data is 16-bit due to a historical botch, so we use
         * magic 16's instead of ICU_LEN and can't support 24 interrupts
         * under SMP.

This is right before the code that checks the irq:

                if (intr < 0 || intr >= 16)
                        return (EINVAL);

I doubt this will be changed as it is gone in 5.X (thanks to the new
entropy gathering in -CURRENT).
