Pass1 BCM1250's have enough problems that it's no surprise that things don't work anymore. Most of the workarounds to CPU core issues are deliberately not checked into the external (linux-mips) tree, and some require some nasty toolchain hacks (for example, taking exceptions on the instruction in a branch delay slot is perilous).
I don't know how you got your SWARM, but you might want to press for getting a new one. No pass1's were ever shipped in volume, so it would be best to NOT support it.
