It's a limit of the kernel.

A possible solution might be the patch from:

  http://lwn.net/Articles/110426/

But we have to review and test that one. It's on the todolist:
http://bts.grml.org/grml/issue42 - but it's definitely queued for
post 0.9, we had the full freeze for grml 0.9 and grml-small 0.3
right in those minutes. And 2.6.19 will have some further changes
due to Libata PATA merge as well....
