Thanks, your guess is right ;-) I got that one one fixed. What I got now 
is a complaint:

mipsIRQ.S: Assembler messages:
mipsIRQ.S:116: Error: absolute expression required `li'
mipsIRQ.S:120: Error: absolute expression required `and'
mipsIRQ.S:127: Error: absolute expression required `and'

the trouble causing code is this (STATUS_IE) :

LEAF(mips_int_lock)
        .set noreorder
        mfc0    v0, CP0_STATUS
        li              v1, ~STATUS_IE
        and             v1, v1, v0
        mtc0    v1, CP0_STATUS
        j               ra
        and             v0, v0, STATUS_IE
        .set reorder
END(mips_int_lock)


LEAF(mips_int_unlock)
        mfc0    v0, CP0_STATUS
        and             a0, a0, STATUS_IE
        or              v0, v0, a0
        mtc0    v0, CP0_STATUS
        j               ra
        nop
END(mips_int_unlock)

Any hints here ?
