Sorry, I can't help you with these, try posting this information to=20
freebsd-stable list.

You can have a kernel without umass, but with uhid, ukbd, ums and other=20
USB device drivers. When you need to access a USB device (after boot)=20
you can just load the kernel module (umass.ko), wait the timeout and=20
continue using it. I think the embedded CD/DVD drive in the chassis=20
presents itself as a USB device so when you build a kernel without=20
umass, you won't be able to access it (until you load the kernel module, =

of course).

Yes, very likely.
