Of course. I wouldn't even *try* to do sth other. In fact, I'm looking
around for various specs of various implementations (as seen from
the bus) of the LANCE chip to see if I could manage the job to
unify them all together:

Driver file                                   | Mentioned Chip
./xxx/declance.c        # as for DS5k/200
./drivers/net/bagetlance.c                      none mentioned
./drivers/net/sk_g16.c                          Am7990
./drivers/net/ni65.c                            ni6510 aka Am7990
./drivers/net/ewk3.c                            Am7990
./drivers/net/sk_mca.c                          Am7990
./drivers/net/sunlance.c                        NCR92c990
        `-> Father of declance.c as I think
./drivers/net/sunhme.c                          none mentioned
        `-> *some* cards seem to be compatible?!
./drivers/net/a2065.c                           Am7990
./drivers/net/ariadne.c                         Am79c960
./drivers/net/atarilance.c                      none mentioned
./drivers/net/sunqu.c                           "looks like LANCE"
./drivers/net/atari_pamsnet.c                   none mentioned
./drivers/net/lance.c                           Am7990, Am79c970A
./drivers/net/pcnet32.c                         none mentioned
./drivers/net/sgiseeq.c                         Seeq8003 (different buffer
                                                layout for speed)
./drivers/net/am79c961a.c                       Am79c961A
./drivers/net/sun3lance.c                       none mentioned, but adopted 
from sunlance.c
./drivers/net/pcmcia/nmclan_cs.c                Am79c90
./drivers/net/ibmlana.c                         "start of LANCE"
./drivers/net/7990.c            *** GENERIC ROUTINES!!! ***
./drivers/net/hplance.c                         Uses 7990.c!
./drivers/net/mvme147.c                         Uses 7990.c!

I really *hate* to see so many different implementations. That counts
to about 21..25 pieces of code, always written for the same thing.
Well, I'll start off in merging in those two declance drivers. But
this will come no earlier that in two weeks or so. I'll first do
the serial keyboard with dz.c.

PS: Looking at ~23 Am7990 and ~5 Z8530 drivers I think I should go to
    *BSD :-) Who will ever attempt to clean up?
