Hi all,
My first post here and I'm already in trouble 
Here's the issue:
When I boot from a rescueCD (Linux sysresccd 3.2.18 ) I get the following entry with lspci -k:
| Code: | 00:14.0 SMBus: Advanced Micro Devices [AMD] nee ATI SBx00 SMBus Controller (rev 3c)
Subsystem: ASRock Incorporation Device 4385
Kernel modules: sp5100_tco, i2c-piix4
|
However when I boot into my new gentoo installation, with manually compiled kernel, there's no mention of the 2 drivers when I do lspci -k.
I checked the /usr/src/linux/.config for the kernel and there are these entries
| Code: | CONFIG_I2C_PIIX4=y
CONFIG_SP5100_TCO=y
|
So I did compile them into the kernel.
What am I doing wrong?
Thank you.

| It's a fresh install so /dev/sda1 was mounted to /mnt/gentoo/boot, as per the Handbook. |

Check your bootlog.
The highest probability is that you can read your smbus driver being disabled.
This will be because the kernel detects that something else (in that case the BIOS) also accesses the device.
In case of conflicts, the default policy is to disable the in-kernel driver.

Either I'm missing something or there is no reference to SMBus.

On the other hand, If there would be a conflict, wouldn't that deactivate the modules for the livecd as well? |

Jaglover and aCOSwt thanks for the replies.
I "solved" it by building both i2c-piix4 and sp5100_tco as modules.
Now they show up in lspci -k |
