Well, the results of various experiments:

Firstly, (and this is before applying patches 31798 and 31799) the white screen
phenomenon not always occur, but fonts corruption and freezing always do.

After applying patch 31798 (force 32 mb gart) nothing significantly different
happened. Applying patch 31799 (setup gart like pre-kms) on top of all other
four, aggravated the problem: more corruption not only in fonts, also in other
areas like windows titles and desktop background (plus freeze). Applying patch
31799 without applying 31798 on top of previous three, maintains the same
symptoms previous to the last two patches: font corruption and freeze.

I also noticed that when applied both patches, GDM shown some rectangles in the
background and a corruption similar to those on the fonts but in the form of
random horizontal thick noisy bars with many colors.
