I just tried, with switching my loongson to kern/subr_disk_mbr.c.
It mostly works, but it seeems that the disklabel and mbr
data structure overwrite each others: when I write a new disklabel
I loose the first 2 mbr partitions, and when I write a mbr with
fdisk, disklabel complains about invalid partition 'p' which I never
entered.
This is probably because of:
#define LABELSECTOR     0                       /* sector containing label */
#define LABELOFFSET     64                      /* offset of label in sector */

in evbmips's disklabel.h. LABELSECTOR may be OK but LABELOFFSET may needs to
be changed. Or maybe something has to be changed in disklabel(8),
I didn't look further yet.
