Hmmm, from the source code in NetBSD:

 * Tuner Notes:
 * Programming the tuner properly is quite complicated.
 * Here are some notes, based on a FM1246 data sheet for a PAL-I tuner.
 * The tuner (front end) covers 45.75 MHz - 855.25 MHz and an FM band of
 * 87.5 MHz to 108.0 MHz.

And I found a check for BKTR_RADIO_NOFREQCHECK in one of the kernel
source code which you could try to set and see if it works now.
There is a check for 8750 inside this ifndef.
