Looks like product datasheets for tuners containing STB0899 are
suggesting specification for min. symbol rate of 2MS/s.
Some specs found here, all suggesting 2MS/s for min. symbol rate:
Comtech DVBS2-6899

New patch:
This makes minimum symbol rate driver capabilities on par with some
accessible datasheet specifications*, and allows tuning on linux to
transponders that have symbol rate between 2000000-5000000, too.
Patch was tested successfully on Eutelsat 16A transponders that
became reachable with it (2000000 < symbol rate < 5000000):
* DVB/S 12507050 V 2532000 3/4
* DVB/S2 12574000 V 4355000 3/4 8PSK
* DVB/S 12593000 V 2500000 2/3
* DVB/S 12596940 V 2848000 2/3
* DVB/S 12600750 V 2500000 1/2
* DVB/S 12675590 H 4248000 3/4
