yes, this is confirmed also by others.

The missing range is from 359.25 (S28) to 399.25 (S33) then.
The tuner TUNER_ALPS_TSBE5_PAL you use in compatibility mode has the
following ranges.
static struct tuner_range tuner_alps_tsb_5_pal_ranges[] = {
{ 16 * 133.25 /*MHz*/, 0x8e, 0x01, },
{ 16 * 351.25 /*MHz*/, 0x8e, 0x02, },
{ 16 * 999.99 , 0x8e, 0x08, },
};
The missing channels are currently handled in UHF mode, but obviously
have to be within VHF HIGH. Change the 351.25 to 399.25.
Until now no missing channels for such PAL tuner types have been
reported and I wonder if it is a new type or if the others just had no
broadcast in that region. The NTSC variant seems to get all channels
with tuner=66 ntsc_ranges so far.

With recent kernels you need to enable saa7134-oss and saa7134-alsa as
modules and load them separately or install a mercurial snapshot, also
e.g. some 2.6.15 distro kernels don't have it enabled.
You should get your missing dsp and mixer devices then. (modinfo
saa7134-oss etc)
Cheers,
