Bugzilla Bug 26848

I can't emerge lm-sensors on a fresh 1.4 install. All I2C modules has been
compiled 
successfully with gentoo-sources-2.4.20-r6. 


Reproducible: Always
Steps to Reproduce:
1. emerge lm-sensors 
2. 
3. 
Actual Results:

I got this error even when I disabled I2C from kernel-config section "I2C
Device Support", however I'd acually enabled it under 'Character Devices
-> I2C Support"
might be worth a look, it appears that the forum-link addresses another problem.

here's the clue:
kernel/busses/i2c-amd8111.c:25:2: #error Your i2c is too old - i2c-2.7.0
or greater

that the error message is printed includes "kernel\nversion" should also
be considered a bug, as the function used obviously does not handle '\n'
as the maintainer of this package thought it would..
