No there is no such an option. Perfmon is a kernel compile time option.

This should not happen at boot time.
I don't know what is in UL (United Linux?)?
Could you try with a more recent kernel 2.4.21 from Bjorn?

I remember seeing this kind of error when playing with using
PAL_HALT_LIGHT in the cpu_idle loop. Newer PAL solved the
problem. If you have CONFIG_IA64_PAL_IDLE turned on in your
config file, you either need to upgrade to new firmware (not
sure what rev to recommend on a tiger box) or disable the config
option and rebuild a kernel. Try for PAL 7.40 or better.
Thanks,
Alex

Latest BIOS for Tiger is S870BN4A.86B.0898.P07.0305300848 which
includes PAL 7.59
