Hi!

I read my dmesg output in more detail and found some entries I'm
wondering about. I have all acpi stuff enabled except for com, fdc,
and lpt.

Can someone please shed a light on these -- what are they, do they
even need drivers, ...

nfe picks up a ukphy even though I have all phys enabled (from GENERIC/amd64):

What about these?

And a last thing:
I recently attached a PS/2 keyboard (since USB keyboards don't work in
ddb). Since then, starting X takes longer and dmesg then contains:
pckbport: command timeout
pms_enable: command error 35
pckbport: command timeout
pckbport: command timeout
pms_disable: command error
pckbport: command timeout
pms_enable: command error 35

grep pck says:
pckbc1 at acpi0 (PS2K, PNP0303): kbd port
pckbc1: io 0x60,0x64 irq 1
pckbd: error setting scanset 2
pckbd0 at pckbc1 (kbd slot)
pckbc1: using irq 1 for kbd slot
wskbd0 at pckbd0: console keyboard
pms0 at pckbc1 (aux slot)
pckbc1: unable to establish interrupt for aux slot

Seems it looks for a PS/2 mouse as well, but why doesn't it remember
that there is none?
