New if_zyd driver

Hi,

I'd like to report success with new zyd driver, and to thank the
author for his work.

I had tried the diff that was published previously. With ifconfig,
the device associated with the access-point, but no traffic was
possible. With the files now included in CVS, the device works!

However, the stick needs to be inserted after booting up. Then I can
also remove the stick without ill effects (for logmessages see below).

When the stick is present during boot, the log shows:
 Aug 30 15:25:17 lapje kernel: zyd0: <ZyDAS USB2.0 WLAN, class 255/255, rev 2.00/48.10, addr 2> on uhub4
 Aug 30 15:25:17 lapje kernel: zyd0: setting config no failed
and there are 2 problems:
1. "ifconfig -a" shows no zyd0 device.
2. when the stick is removed, the laptop panics (page fault)

Perhaps useful, the logs after inserting the stick, thus
when it gets to work fine (despite the "Unknown" message).
