Note zaudio(4) doesn't work on 8.x (devices are attached, but fails to
playing sound) but it's a bit hard to fix without isaki-audio2 branch.

More issue on 9.0_BETA:

(1) options WSDISPLAY_COMPAT_RAWKBD for Xorg server

On 9.0_BETA, options WSDISPLAY_COMPAT_RAWKBD is commented out
in zaurus/conf/GENERIC, but it's necessary to use Xorg server.

I'll put it back to GENERIC and send a pullup request.

(2) zrc.c fails to build with options WSDISPLAY_COMPAT_RAWKBD

When I enable options WSDISPLAY_COMPAT_RAWKBD arch/zaurus/dev/zrc.c
gets build error, undefined symbols RAWKEY_Null, RAWKEY_AudioMute,
RAWKEY_AudioLower, and RAWKEY_AudioRaise.

On 8.x and prior, it happens to work because zrc.c doesn't
explicitly include "opt_wsdisplay_compat.h" and the option
WSDISPLAY_COMPAT_RAWKBD is not pulled properly. (Oh well)

With the following fixes Xorg server functional with audio:

(though rotation problem on 8.x is not addressed yet)

I'll also send a pullup request for zrc.c for both netbsd-8
and netbsd-9:
