in my kernel tree i find

That seems to be something different.
(That are  "original" kernels from kernel.org.)



but:
 i am running ( i hope.. why there is
an info-field in the module header, and only authors eMail address 
is allowed there. Not very "transparent".)


/* $id: i2c-core.c,v 1.64 2001/08/13 01:35:56 mds exp $ */

took from the i2c-2.6.1 package

i do have only version 2.4.8 to 2.4.10 on my machine to compare.

between 1.58 and 1.64 are a lot of differences.

i did not apply the i2c-patch to the kernel but
use the drivers from the i2c paket directly.
