I just encountered the exact same problem.  I kludged around it temporarily
by ifdefing out the couple of places in if_hubmod.c where the macro
HUBMAXPKT was used.  As far as I could see from the comments, they were both
testing conditions that "should never happen anyway".

With those modules recompiled and running in a 1.5W kernel, I can report
that vmware now gets further than it did with a 1.5U kernel when installing
windows 98 in a virtual disk.  It now seems to complete the install fine,
whereas before it wedged part way through the install.

I haven't exercised the windows installation much, so I can't yet comment
on how reliably it works.
