2.4 + generic HDLC update? Any ideas?

The question is probably aimed mainly at people maintaining 2.4 Linux
and/or networking, but I'd like to see an opinion of other users/
developers as well.

What do you think about updating the 2.4 generic HDLC layer to the
newer 2.5 code?

- it would break all sethdlc compatibility, users would be required to
  get 2.5 sethdlc.c and recompile it. There are even cosmetic sethdlc
  syntax changes and additions (sethdlc is a configuration tool).
- it would make it possible to support new boards like Cyclades PC300
  (not only this one).
- drivers which are in current 2.4 include Moxa C101 and RISCom/N2,
  which are older ISA cards. Most of their users currently use 2.5
  generic HDLC (a patch) with 2.4 kernels anyway.
- the other driver affected is DSCC4, but I know exactly nothing about
  it (a 2.5 version of it is, of course, available). What do you think,

The update, if any, wouldn't take place yet. I would expect it to happen
after some remaining questions regarding 2.5 code are resolved - chances
are there will be small changes to 2.5 generic HDLC interface first.
