An upgrade from 3.81-r2 causes the following error when trying to compile linux kernel sources: linux-2.6.25.20 # make bzImage Makefile:1523: *** mixed implicit and normal rules.

That's correct behavior and old Linux sources, like 2.6.25 and 2.6.26 are broken. Not much we can do about that.
Have opened https://bugzilla.kernel.org/show_bug.cgi?id=21642 , let's hope it gets fixed by upstream. Thanks.

Thanks. > well, according to http://www.kernel.org/ the 2.6.27 branch seems to be still maintained, perhaps it works out of box? or is likely to be fixed. I think trying to get 2.6.25 or 2.6.26 fixed is a lost cause
The make issue does not happen for me with 2.6.27.54. :( Unfortunately, I have to go backwards to find out when the serial modem support got broken. With the move from OSS to ALSA support something got screwed in slmodem, and it is not used by many users anymore. It is enough to be restrained by udev on my installation that I have to use kernel above 2.6.25. :((
