I was afraid you were going to say that.

I compiled the kernel without module support so unless there's some sysfs trick that can be done...

For some reason I thought I had once seen an 804 BIOS but I only see 802 on the EeePC 900 page (link below) and the even older 704 BIOS on ftp://ftp.asus.com/pub/ASUS/EeePC/EeePC900/ .

The Xandros 2.6.21.4-eeepc install has the following files in /proc/acpi/asus/ brn camera cardr cpufv disp hdps init type wlan
I have no idea what cpufv, disp, hdps, init or type are. Doing echo 1 > camera && echo 0 > camera under this setup does NOT disappear the SD card. Additionally brn seems to really represent the current LCD brightness (whereas it does not on a stock kernel and seems to always be set to -19) and the hotkeys (e.g. for brightness) seem to respond far more quickly than the stock kernel too.

2.6Gbytes of multipart RAR. Joy.

This link seems to be for the 701 only.
Does anyone know if the archives on http://support.asus.com/download/download_item_4.aspx?product=20&model=Eee%20PC%20900/Linux&SLanguage=en-us&os=5 (release dates appear to be 5th September 2008) are actually any different?
(A brief aside. If you are a company doing seeking to do a source release of a Linux distribution, it might be a good idea to go for typical Unix formats. It is easier for folks if you package things as tar.bz2 or tar.gz files or even .zip rather than going for .rar . Additionally it is helpful if you split the just the kernel into an archive of its own).
