I never tried a 5000/200. You could try to use my kernel images, which
are available at my web site (Use the ELF kernel). That one I've tested
on a 3100, a 5000/150, and a 5000/260. It doesn't contain
your esp patch, because activating the TC SCSI card results in a SCSI hang
during boot at my system (or do you think that's fixed now?).

One thing you could check is in arch/mips/dec/prom/init.c
There should be the following code (near line 86):

        which_prom(magic, prom_vec);

        if (magic == REX_PROM_MAGIC)
            rex_clear_cache();
