MPC8xx SCC for sync. HDLC on 2.4 kernel

I am trying to build a synchronous HDLC driver for the SCC of the MPC850/860
under linux kernel 2.4.22

I have got one working on a 2.2.5 kernel and one buggy, async only, for the 2.4
What would be the best approach: porting the 2.2.5 driver to the 2.4.x kernel or
digging into the driver (ehdlc.c by Rodolfo Giometti based on Dan Malek's
enet.c) to make it work for sync HDLC at high speeds?

Or an alternative?

Best regards,

Jos Beck
