I would not replace a working gdal version with a probably not working

mine. You could double-check again if your gdalinfo still finds a
raster attribute table, then import with r.in.gdal.
Out of curiosity: if a table contains several columns which one(s) is/are
imported and in what form do they appear in GRASS (I don't have a file here
to test myself) ?
Each column has a dedicated usage. For "name" usage, the column is
treated as category labels. For any of the color usages, the column is
treated as corresponding red, green, or blue color. See also the gdal
documentation [0]. Currently, r.out.gdal exports category labels or
color rules to a raster attribute table with the new -t flag, and
r.in.gdal automatically imports any information it finds.

So, IIUC you get the GFU_Name and the color information, but if the
table contains several fields (which I guess will be of type
GFU_Generic) these are ignored ?
