As long as they are the raw USGS DRG's, and not the MrSID-compressed versions, you should be fine.  You'll need the .tif and the .fgd files only.

For this you'll need tif, geotiff, and proj4 libraries, installed in the proper order (geotiff must be built with proj4 support).

I don't know if the Ubuntu instructions give you a working geotiff installation.  I'm using OpenSuSE.  Check the "INSTALL" file that comes with Xastir for more details on the library installs for geotiff.
