how to get irq information ?

Hello,
  i use a GENERIC kernel and i want to get more
information about my jornada 660lx.
(i use this kernel:
ftp://ftp.netbsd.org/pub/NetBSD/NetBSD-3.1/hpcsh/binary/kern
el/netbsd-GENERIC.gz
 and dmesg does not say much.)

  How can i get information about irqs and base
addresses? Should i use another kernel for that?

Thanks in advance.

Regards,
Rafael
