Plain CDROMs, CDRs, and CDRWs, yes. I haven't tried reading a DVD
from FreeBSD.

Let's try that again:

dd: /dev/acd0c: Input/output error

Much better.

It's a winmodem -- don't bother. Delete it from your order.

Don't know.
I don't know if it works, but the USB port is detected as:
uhci0: <Intel 82371AB/EB (PIIX4) USB controller> irq 5 at device 7.2 on pci0
usb0: <Intel 82371AB/EB (PIIX4) USB controller> on uhci0
usb0: USB revision 1.0
uhub0: Intel UHCI root hub, class 9/0, rev 1.00/1.00, addr 1
uhub0: 2 ports with 2 removable, self powered
[ Like other laptops, the Inspiron has only one USB port in the back. I
assume that the port replicator has two. ]
A potentially big issue is that the USB and sound IRQs appear to be
tied together, and there seems to be no way to change this (or even
specify which shared IRQ to use). The Inspiron uses the Phoenix BIOS,
and other laptops that use this same BIOS allow you to set all aspects
of the USB and sound devices. The Inspiron doesn't though.
I haven't tried the IRDA port, but it looks like it can be
configured as COM2 from the BIOS, and so it may work.

Note that the Inspiron is large and heavy (~9.5 lbs). It doesn't
bother me, but it bothers some. If you carry it around a lot, you'll
need a good (and large) carrying case.
