Hm, now I cannot select LGUEST as a module any more:

$ make clean && time make
   [...]
   HOSTCC  scripts/kconfig/zconf.tab.o
   HOSTLD  scripts/kconfig/conf
scripts/kconfig/conf -s arch/x86/Kconfig
.config:1793:warning: symbol value 'm' invalid for LGUEST
   [...]
   Linux hypervisor (LGUEST) [Y/n/?] (NEW)

Is this intentional? I've tried your patch with or without Rusty's patch, 
both gave me the same results. My .config:
http://nerdbynature.de/bits/2.6.25-rc2/lguest/

Thanks,
Christian.
