In arch/x86_64/ia32/ia32entry.S, both the vm86 calls (vm86 and vm86old)
are stubbed to sys32_vm86_warning, which just printks "vm86 mode not
supported on 64 bit kernel" and then returns -ENOSYS.
This is moderately likely to bite people on X - the 32 bit packages will
use vm86 to make VESA calls, and a surprising number of drivers use VESA
