the problem with vmap handling was fixed on i386 last year iirc (but definitely
later than your .28, that's very old ;), on amd64 only recently after we'd talked
to a vmware engineer.
so in general .32+ should work, as far as this problem is concerned. unfortunately
i couldn't find a working ebuild for vmware 7 yet, so i can't tell if there're more
problems or not.
