I tried things out with your patches, and without the overrides in my
config file. Unfortunately, it didn't probe correctly:
bktr0: <BrookTree 848> rev 0x11 int a irq 17 on pci0.11.0
bti2c0: <bt848 Hard/Soft I2C controller>
iicbb0 on bti2c0
iicbus0 on iicbb0 master-only
smbus0 on bti2c0
smb0: <LM75/78> on smbus0 addr 0x92
Miro TV, Temic NTSC tuner, dbx stereo.
It should have said Hauppauge WinCast TV, Philips NTSC tuner.

Well, it did with the old (October 26th) kernel. Although the values after
that point were all 0xff.
Anyway, let me know if you want me to try anything else.
