The dosemu team does a lot of things well, but occasionally the
development code drops assume non-standard fiddling in the kernel source
:-)). Try the attached patch - it works for me. Will someone on the
dosemu team please get back to me if this is not correct? Thanks.

p.s. - This patch is against release kernel 2.0.0!
