I was faced with same problem on my laptop. Adding printf() into main()
before dsk = malloc(sizeof(struct dsk)); fix boot. Yesterday, avg_at_ proposed
patch:
Index: /usr/src/sys/boot/i386/zfsboot/zfsboot.c
===================================================================
--- /usr/src/sys/boot/i386/zfsboot/zfsboot.c    (revision 248421)
+++ /usr/src/sys/boot/i386/zfsboot/zfsboot.c    (working copy)
_at__at_ -302,6 +302,7 _at__at_
      * region in the SMAP, use the last 3MB of 'extended' memory as a
      * high heap candidate.
      */
+       high_heap_size = 0;
     if (bios_extmem >= HEAP_MIN && high_heap_size < HEAP_MIN) {
        high_heap_size = HEAP_MIN;
        high_heap_base = bios_extmem + 0x100000 - HEAP_MIN;

it works for me, without printf() :) Can you test it ?
