 I had the same problem which went away after removing TFTP support and =
 reinstalling the bootcode.=20
 For now I suggest to add the following patch:
 
 --- sys/boot/i386/loader/conf.c.orig	2010-02-13 14:08:31.154391969 =
 +0000
 +++ sys/boot/i386/loader/conf.c	2010-02-13 14:11:11.119255786 +0000
 @@ -46,6 +46,10 @@
  #error "Cannot have both tftp and nfs support yet."

 +#if defined(LOADER_ZFS_SUPPORT) && defined(LOADER_TFTP_SUPPORT)
 +#error "Cannot have both tftp and zfs support yet."
 +#endif
 +
  #if defined(LOADER_FIREWIRE_SUPPORT)
  extern struct devsw fwohci;
  #endif
 
 I think having both options corrupt each other's environment=20
