Most USB chips work with hci_usb driver.

Try hcitool scan
Make sure you have installed the bluetooth userspace tools. Debian provides
a metapackage called bluetooth to do that.

eben@kong:~$ lsusb
eben@kong:~$

Even if it's internal, it's still USB?

eben@kong:~$ lsmod | grep hci
hci_usb 16668 0
bluetooth 50404 1 hci_usb
ehci_hcd 30988 0
uhci_hcd 23052 0
usbcore 120068 5 hci_usb,usb_storage,ehci_hcd,uhci_hcd

OK, it loads with no complaints.

Synaptic says it's installed. Could hci_usb be one of those modules
that gets hosed by suspending? I'll check after a restart to see if it
acts the same.

Since I custom-specced this machine, maybe I screwed up and ordered a
NIC without BT. I'll check the BIOS to see if it has a good reason
nothing shows up.

That's not listing anything at all. It should list the root hub(s).

The one on my Thinkpad T42p appears as a USB device. That one is
inactive by default; I have to press Fn-F5 to activate it. When I do
that, a Bluetooth LED near the NumLock LED lights up, and the device is
visible on lsusb. (Yes, it works properly, but I don't have much use
for it as I only have 1 Bluetooth-capable device.)

Sounds like it's inactive if it's there. Check your laptop's manual for
info on Bluetooth. Since Bluetooth uses power, a lot of the time,
laptops have switches of some sort to turn it on/off. That means you
don't waste valuable battery minutes running Bluetooth when you don't
need it. HTH anyway,
