[R-sig-Geo] Large Lidar Data Set fill 1m gap

I used GRASS with the inverse distance weighted algorithm to make DEMs
@ 1m resolution (I have a 5GB xyz text file also).  There ~40
individual DEMs with a 1m gap in between them.  I would like to fill
this 1m gap and then patch all of the DEMs together.  r.fill.nulls in
GRASS will throws an error that I believe is due to memory limitation.
 Any hints or leads would be greatly appreciated.

System Inoformation:
Linux Ubuntu 10.04
R 2.11.1
GRASS 6.4svn (a couple of days ago)

kindest regards,

Let's not spend our time and resources thinking about things that are
so little or so large that all they really do for us is puff us up and
make us feel like gods.  We are mammals, and have not exhausted the
annoying little problems of being mammals.
