bktr driver, unknown Hauppauge tuner 0x79 -- fix enclosed

[KRTEN, Robert]

Hi folks,

I found an unsupported tuner, Hauppauge 0x79, and hacked a quick fix into bktr_tuner.c,
and I'm hoping someone can "officially" add it to the release.

The 0x79 tuner is a TDA6503ATS chip, and it looks like the "band-switch
values" need to be set to 1,2,8 (instead of, say, 0xa0, 0x90, 0x30 for the
Philips NTSC entry).  This is for the "WinTV GO Plus" card available in Canada;
with this hack, it works, but I'm not yet 100% certain that these are the 
"absolutely positively correct values", because they are tied to the four ports
(what I'm saying is, I'm not 100% sure that "8" is the right value, it may
actually need to be 12, but I don't know what all the bits do).

Please reply to rk at parse.com; I'm using my work account because I'm an inept
sendmail admin and can't get the HELO to say "parse.com" instead of "amd64.ott.parse.com"
which @freebsd.org rejects as an invalid domain.  Sigh :-)

Cheers,
-RK
