They indeed have, and probably not insignificant.

ftp://ftp5.gwdg.de/pub/linux/misc/suser-jengelh/SUSE-10.3/ (and
../SRPMS/) contains ch341-2.6.23.99rc7-1593.{i586,x86_64,src}.rpm for
2.6.23(.17) (and such kernel is available through this repository).
Maybe it helps though you said you have 10.2.

Well yes it's SUSE10.2 with 2.6.18. I know the '-mm' ch341 patch was 
applied to 2.6.23 which already had the data structure changes.. The 
problem for me is I have a bunch of  softwares that require kernel 
modules to work (fpga stuff, X11, etc..), it's a pain to rebuild every 
other modules if I could only get ch341  to work with 2.6.18 kernel.

Hi Jan, thanks for the info. I didn't find this gem until today when I 
am cleaning up my emails...

Cheers,

Maybe it helps though you said you have 10.2.

A question to Frank Kingswood about ch340/341 support for 2.4.18 kernel

Hello Frank,

 Is there any chance this driver can be back ported to 2.6.18 for 
opensuse 10.2 system? It seems the usb kernel data structures had some 
significant changes from 2.6.18 to 2.6.24. I couldn't hack it to work 
with 2.6.18 after some effort. It'd be really great to be able to use 
this cable on Linux with kernels older than 2.6.24. I can also be 
pointed to the right direction to port this drive back if it does not 
require a significant amount of work (apart from young kid and work).
