Bluetooth on 5.0.1

[Radek Kujawa <rkujawa%c0ff33.net@localhost>]

Hi list.

I recently upgraded my PowerMac G3 B&W to NetBSD 5.0.1, and thought 
that's great opportunity to try out Bluetooth support. So I recompiled 
kernel with necessary devices like ubt, bt*.

I had partial success with Apple Wireless Keyboard (small alu model). 
After somewhat lenghty configuration, it's possible to use this keyboard 
in text mode, and it "just" works. However, there's one really annoying 
bug - pressing caps lock triggers kernel panic:

It's also impossible to use Xorg with Bluetooth keyboard. Looks like kbd 
driver does not know about WSKBD_TYPE_BLUETOOTH and fails miserably, 
unloading, and therefore disabling all keyboard support. Here's 
interesting part of Xorg.0.log:

(**) Option "CoreKeyboard"
(**) Keyboard0: always reports core events
(**) Option "Protocol" "wskbd"
(**) Keyboard0: Protocol: wskbd
(**) Option "Device" "/dev/wskbd0"
(EE) Keyboard0: Unsupported wskbd type "21"(EE) PreInit failed for input 
device "Keyboard0"
(II) UnloadModule: "kbd"
