There are a few tuner related fixes in 3.0a11 that may be of benefit to you:
1) Left/right tuning on the front buttons now works.
2) RDS/AF can now be turned off.
3) Some of the AF switching parameters are exposed in config.ini

With 3.0a11 I get the occasional segfault that in turn causes a reboot. I've only noticed this in tuner mode myself and it only happens about once a week.
