I can't say much about the 600, but almost all ThinkPads (back to the
500 series) allow PCI interrupts to be adjusted in BIOS using the ps2
utility. My 600E allowed the use of about 3 irqs.

ps2 is a DOS tool that can be run under Windows or be written to a
bootable floppy. It is how almost all BIOS stuff is adjusted on
them. The boot-time BIOS stuff is almost non-existent.

ps2 is available from the Lenovo/IBM web site.
