Assuming this is a Linux kernel, have you tried looking in the /sys filesystem?

It's all driver and device specific, so I can't give you any better answers in this case off-hand, but here's some examples from a system of mine with FC storage:
Code:
$ readlink /sys/block/sda
../devices/pci0000:00/0000:00:02.0/0000:09:00.0/0000:0a:00.0/0000:0b:00.0/host2/rport-2:0-0/target2:0:0/2:0:0:1/block/sda
$ readlink /sys/block/sda/device
../../../2:0:0:1

That is *much* easier to parse...

dahdi_hardware

DAHDI_HARDWARE(8)					User Contributed Perl Documentation					 DAHDI_HARDWARE(8)

NAME

       dahdi_hardware - Shows Dahdi hardware devices.

SYNOPSIS

       dahdi_hardware [-v][-x]

OPTIONS

       -v  Verbose ouput - show spans used by each device etc. Currently only implemented for the Xorcom Astribank.

       -x  Show disconnected Astribank unit, if any.

DESCRIPTION

       Show all dahdi hardware devices. Devices are recognized according to lists of PCI and USB IDs in Dahdi::Hardware::PCI.pm and
       Dahdi::Hardware::USB.pm . For PCI it is possible to detect by sub-vendor and sub-product ID as well.

       The first output column is the connector: a bus specific field that shows where this device is.

       The second field shows which driver should handle the device. a "-" sign marks that the device is not yet handled by this driver. A "+"
       sign means that the device is handled by the driver.

       For the Xorcom Astribank (and in the future: for other Dahdi devices) some further information is provided from the driver. Those extra
       lines always begin with spaces.

       Example output:
