15 the problem with vmap handling was fixed on i386 last year iirc (but definitely
16 later than your .28, that's very old ;), on amd64 only recently after we'd talked

19 so in general .32+ should work, as far as this problem is concerned. unfortunately
20 i couldn't find a working ebuild for vmware 7 yet, so i can't tell if there're more
21 problems or not.
