Here's a sample of the *.las files I'm using (this one is only 260k):

Both r.in.lidar and v.in.lidar say that none of the 7651 points in
that file is valid. I am using libLAS 1.7.0 with GeoTIFF 1.4.0 GDAL
1.10.0 LASzip 2.1.0. I remember that [r|v].in.lidar require a recent
version of libLAS and other users experienced problems with older
versions of libLAS. Which version are you using?

In the lasinfo output I don't see anything unusual (other than z values <
0). The *.las are projected into our local tmerc CRS.
I can run las2txt and then import the text file with v.in.ascii, but I'd
like to work out what's wrong with the direct raster import. Any ideas how
to further debug this?

You can try gdb, see also the GRASS wiki [0].
