MIHIRA Sanpei Yoshiro 2a2e255b8a add -I option, ``Don't get and use a list of free 
IRQs from kernel.''..

With IBM ThinkPad600.  ``sio1'' was disabled in BIOS
and irq 3 was free (also not listed in dmesg), I think.
But I could not use irq 3 for PC-Card with new(PIOCSRESOURCE
ioctl enabled) pccardd.
