[ltp] paging request BUG in 2.6.19-rc5 on resume - X60s

[Martin Lorenz]

Hallo again,

here is another one:

I reported a black screen on resume with my latest kernel build earlyer. But
this was not reproducible. Only occured once.

BUT I suspended with the ipw3945 module loaded once again now and got a BUG
report in the log instead of a black screen.

I only see this when ipw3945 is loaded.
