[OOPS] 2.5.71 svgatextmode

[Samium Gromoff]

Just a call to svgatextmode causes this in both 2.5.71,72, on 4 different boxes:

--ksymoops 2.4.8 on i686 2.5.71.  Options used
     -V (default)
     -k /proc/ksyms (default)
     -l /proc/modules (default)
     -o /lib/modules/2.5.71/ (default)
     -m /boot/System.map-2.5.71 (specified)

Error (regular_file): read_ksyms stat /proc/ksyms failed
No modules in ksyms, skipping objects
