I've prepared a series of patches that remove quite a bit of code that
AFAICT is no longer used. It is code specific to the 2.4 kernel series,
code that used discover for hardware detection, and code to support old
versions of udev.
Removing this code should not affect the current functioning of the
installer, but as it still is quite invasive I'd appreciate a review
before committing.
The patches for hw-detect have been split out into 4 stages:
01: removes 2.4 specific code
02: removes support for discover; the blacklisting code for the de4x5
module is obsolete as that module has no PCI ID's associated with it
03: cleans up udev support
04: some final bits
I suspect that there is quite a bit more code in hw-detect that can be
removed because some modules will now be reliably loaded automatically by
the kernel/udev, but that is for later.
Cheers,
FJP
