OK, I wasn't sure so I asked. Yes, I changed the tools.

I have been able to build a 2.4.2 kernel but I can't make it run.

I have also steped up to the latest kernel in cvs. Having a bit more trouble
with that:

mipsel-linux-gcc -I /opt/mips/linux-2.4.3/include/asm/gcc -D__KERNEL__
-I/opt/mips/linux-2.4.3/include -Wall -Wstrict-prototypes -O2
-fomit-frame-pointer  -G 0 -mno-abicalls -fno-pic -mcpu=r5000 -mips2
-Wa,--trap -pipe    -c -o vgacon.o vgacon.c
