    Linux kernel 2.4 works as a host now.  (I used linux-2.4.0-test9).
      There is a bug as of that version in the Linux kernel header
      file 'include/linux/wrapper.h'.  Macros mem_map_reserve()
      and mem_map_unreserve() do not use the proper parenthesis.
      They are listed as:
 
        #define mem_map_reserve(p) set_bit(PG_reserved, &p->flags)
        #define mem_map_unreserve(p) clear_bit(PG_reserved, &p->flags)
 
      ...but should be:
 
        #define mem_map_reserve(p) set_bit(PG_reserved, &((p)->flags))
        #define mem_map_unreserve(p) clear_bit(PG_reserved, &((p)->flags))
 
      I just used set_bit() and clear_bit() directly to get around using
      these macros.

I will attempt to report this to the Linux kernel team.
