Ok, another tool which is affected by this is procps:

$ ps alx
Warning: /boot/System.map-2.6.9-rc3 not parseable as a System.map
Warning: /boot/System.map not parseable as a System.map
Warning: /usr/src/linux/System.map has an incorrect kernel version.

$ grep -v '\$[adt]' /boot/System.map-2.6.9-rc3 > System.map-2.6.9-rc3

The System.map file is generated by ($1 = vmlinux $2 = System.map):

$NM -n $1 | grep -v '\( [aUw] \)\|\(__crc_\)' > $2

Can we change this to:

$NM -n $1 | grep -v '\( [aUw] \)\|\(__crc_\)\|\( \$[adt]\)' > $2

?
