I have made a quick and dirty patch to fix the output of "ps -lax".
I'll attach the patch. Not a kernel issue, unless Linus changes some
of the new flags...

DESCRIPTION OF DEFECT
Recent kernels use the new flag PF_USEDFPU (0x00100000) that breaks
the three digit format used for "ps -l".
FIX
This patch fixes the format of "ps -lax" for Linux 2.0.
The sulution chosen is to extend the length of the flags field to
six digits. As an alternative, the new flags can be set to zero
(commented).
(This patch has been made against procps-0.99a from the German
S.u.S.E. distribution; fuzz factors may apply.)
