cxm0: unknown tuner code 0x63 - workaround?

[Erin E Conn]

I have a newly-acquired PVR250 and I've installed the driver from ports 
on FreeBSD 6.1-PRERELEASE. The device probing fails with the following 
error:

I gather that whatever rev I got has an unsupported tuner. However, I 
have a digital cable box with S/Video so I'm not planning on using the 
built-in tuner.
Is there a hack or a workaround I could use to at least get the card up 
and running?
I tried adding a case for it in cxm_eeprom.c as was suggested for 
another user in the archives, but all that did was silence the 
complaining that the tuner code was unknown; the device still failed to 
attach.
