Kernel config for Transcend IDE Flash Module

I'm trying to build a minimal custom kernel for my set-top-box (very limited ressources), which I use as home server.

From a recent Arch Live (USB-stick) the Transcend Flash SSD (4GB, 40pin IDE) gets detected as /dev/sda (by the "sd"-driver, I think). The Problem now is that I can't find the kernel settings and always get a kernel panic because it can't find the root device.

Here's the data I have:

lspci (Intel ICH chipset):

dmesg output from the live stick:

The kernel configuration I tried can be found here (from another box running Gentoo).

Any suggestions how I could find the right driver?

Thanks in advance,
