I have run some tests with 8 patches from Linus's 2.6 tree on top of the
2.6.16.25 along with a bit of debug code in the n_tty.c, which ran
perfectly for 3 days.  I now removed the debug code to see if it will
still run perfectly with those 8 patches.  The patches I applied in
order are:

commit 70522e121a521aa09bd0f4e62e1aa68708b798e1
commit 41c28ff1635e71af072c4711ff5fadd5855d48e7
commit 1aef821a6b3aeca8c19d06aee012ed9db617d1e3
commit ee37df7877eeaa16d7761cce64854110a7c17ad9
commit e1a2509023785bd3199ac068ab80155aeba01265
commit 817d6d3bceaf34c99f5343820f9b9e6021f0655c
commit 2c3bb20f46709a0adfa7ea408013edbcab945d5a
commit 33b37a33c242542fac2980b8ccd90977388b7a8d

Hopefully it will stay working, and actually be a solution to my tty
problem in 2.6.16.25.

2.6.18.2 (Debian 2.6.18-4) on the other hand was still broken, but I am
not sure which if any of the above commits are not in that version (the
date ranges made me think they all should be, but maybe I got the date
of 2.6.18 wrong, or not all commits in the linux-2.6 tree are actually
part of a given release.  I am still figuring out git).
