No

OGR could perhaps support it, but it is really libLAS job and I don't think it 
would be wise to reimplement what it does... I'm not sure if a OGR driver 
using libLAS would make sense, and it might be difficult for technical reasons, 
liblas depending - optionnaly - itself on GDAL for SRS support.

Anyway, there's a las2ogr utility in liblas to make the bridge. If you have 
problems, you'd better report them to liblas mailing list.
