We forgot to add it to the GENERIC configuration. Just add
cd* at scsibus? target ? lun ?
and recompile your kernel. You should consider to make your own kernel
configuration anyway, to get rid of all the unused drivers. With 32MB
RAM every saved byte is valuable.

Does it really have to do with your USB attachment? Is it reproducible?
Only with a CDROM drive?

Don't think so. As you see from the dmesg output, the USB and ATA drivers
use different IRQs:
ohci0: interrupting at irq 17
ohci1: interrupting at irq 17
ehci0: interrupting at irq 18
acardide0: using irq 20 for native-PCI interrupt
Maybe all interrupts have been blocked too long for some reason...

Yes, the driver can immediately recover from such a problem.

Probably just a bad connection?
I was very disappointed about the G600's WLAN capabilities. Once I tried
to use it as an access point, but had to realize that the maximum range
is, depending on the client, limited to 2 - 4 meters... :(

I have to admit that I have not much experience with the new kernel modules.
The error message sounds like an authorization problem. Probably you can
only load kernels in securelevel 0 (which usually means before entering
multi-user). Check "sysctl kern.securelevel".
