Some friends and I are doing just that right now.  We're using GDC and its 
extended ASM syntax to write an x86-64 exokernel OS.  It's certainly a lot 
nicer to deal with than vanilla C, and with some of the basic runtime 
elements defined / stubbed out, you don't miss some of the more dynamic 
features that much.  (We haven't gotten dynamic memory or even virtual 
memory implemented yet ;) )
