Agreed. Following patch is against kernel 2.4.14-pre2 and requires none
of my previous patches. What it does:

  * cures all remaining framebuffer and filesystem drivers (including
    shmfs, which lives in drivers/mm) from using strtok()

  * remedies all those warnings regarding the usage of assignments in
    comparisions I introduced earlier

  * contains a real bugfix! ;)

The bug was spotted by Roman Zippel (thanks!): in virgefb.c there is a
'}' missing. My first patch, which went into 2.4.13, did that.
hanks!).

I just hope it's not too big a patch. If so, at least apply the first
chunk (that bugfix), please.

René
