So I got around to downloading those my 4 pieces of rar and poking about 
the source. For those who are curious inside the rars is a tar.bz2 file 
of a tree of .debs. A few hints:

DON'T download the source from China if you aren't in China it's very slow.
The global mirrors are hidden behind javascript for some reason whereas 
the Chinese ones are not. Still don't be tempted if you aren't in Japan 
- the downloads were frequently crawling along at less than 
10Kbyte/second and would periodically disconnect themselves.

The bad news for me is that part4 of the .rar archive was always corrupt 
(I redownloaded it and it was still corrupt). The good news is that I 
was able to extract some of the archive.

Here are the much faster links that worked for me:

In the linux-source deb there is a folder which contains patches against 
2.6.21.4. For short term convenience I have temporarily repackaged the 
patches here: 
http://sucs.org/~sits/test/eeepc-900/eeepc-kernel-patches.tar.gz 
(contains ALSA patches for the realtek intel_hda, the elantech touchpad 
driver, a pci message patch(?), huawei_usb_storage storage patch (?), 
unionfs patches and aufs patches and a kernel config file).

There is also a separate asus-acpi deb which I have temporarily repacked 
on http://sucs.org/~sits/test/eeepc-900/asus-acpi-p9xx_1.2-1_i386.tar.gz 
. Sadly it seems to contain a prebuilt asus_acpi.ko in /lib/modules 
(along with various scripts to respond to hotkeys etc).
