stray irq's in systat

Hi,

	When running 'systat -vmstat 1' on FreeBSD 5.1-CURRENT #1: Mon Aug 25
14:54:14 EDT 2003, the interrupts section shows irq's 0 and 6 as stray. I
remember this would happen on 4.x when I took out lpt drivers from the
kernel, and didn't disable lpt in the bios. This however is not the case,
and start irq's do not show up under 4.8 on this box. everything is working
ok, I am just curious why they are showing up.

# dmesg|grep 'irq 0'
# dmesg|grep 'irq 6'
fdc0: <Enhanced floppy controller (i82077, NE72065 or clone)> port
0x3f7,0x3f4-0x3f5,0x3f2-0x3f3,0x3f0-0x3f1 irq 6 drq 2 on acpi0

Thanks.
