Yes, but better to use GRASS 6.0.1 or 6.1-cvs.

LIDAR data with up to 3 million points has been tested successfully with
the DBF driver and v.in.ascii. 300k points should pose no problem.
I don't have much experience with v.in.db but if anything it should be
smoother although probably has the same memory bottleneck "registering
lines".

Other databases (eg PostgreSQL) might do a better job at dealing with
large datasets. [but I'm not a DB person so don't take my word for it]
