Yep, I'm definitely trying to boot xen.gz (unless the grub menu
extract I showed earlier was wrong)...

Have tried adding printk's and for (;;) {} in kernel.c - that didn't help.

The infinite loops in x86_32.S did make a difference at the following
line though:
    128 start_paging:
    129         mov     $idle_pg_table-__PAGE_OFFSET,%eax
    130         mov     %eax,%cr3
    131         mov     $0x80050033,%eax /* hi-to-lo: PG,AM,WP,NE,ET,MP,PE */
    132         mov     %eax,%cr0
    133         jmp     1f
    134 1:      /* Install relocated selectors (FS/GS unused). */
    135         lgdt    gdt_descr

Adding the 1:  jump 1b before line 132 would make it hang; adding the
line after 132 saw the computer rebooting continuously...  I have no
idea what to make of this though.
