According the pil manual it handles PGM files with "'1', 'L', or 'RGB' data"
which leads me to believe 16bit data is not supported.
You CAN write your own decoder for that though:

It would be trivial to write a decoder for the pgm format.
I have a PGM format image file with 4096 range. When I reads it with
PIL, I get an image with 8-bit values and alternate columns are zero.
Does PIL support reading and writing PGM's with more than 8-bits?
