This was released ten days ago, but here is where you can download the 0.2 version of my Linux distribution for VIA VT8500 based netbooks: [You must be registered and logged in to see this link.]
On the page you will also find the kernel sources (with VIA binary blobs) and the cross compiler toolchain (which runs on x86) to build the kernel.
This distribution runs straight from the SD card; it should not touch Windows CE.
I never tried to access the NAND flash internal to the netbook though.
There are still some major issues and they're mentioned in the readme inside the archive of the distribution. Preparing your SD card for it shouldn't be very hard if you have experience partitioning on Linux.
It is basically this:
1) Login as root, or become it using su, sudo, etc.
2) do two partitions with cfdisk (example: cfdisk /dev/<sd_card_device>) ,
the first will be small and have its type as FAT32
the second will be big and have its type as EXT2
Notice: Replace <sd_card_device> with the device your computer recognizes the SD card as - for example if it were sdc, you would type sdc1.
To format the two partitions:
mkdosfs -F 32 /dev/<sd_card_device>1
mke2fs -v /dev/<sd_card_device>2
3) mount the two partitions
mount -t vfat /dev/<sd_card_device>1 /mnt/<sd_card_device>1 (or any other mount point)
mount /dev/<sd_card_device>2 /mnt/<sd_card_device>2
4) extract fatpart.tgz on the first small fat partition
5) extract ext2part.tgz on the second big fat partition
6) umount the partitions
7) remove the SD card
it should be ready for use, hopefully all will be fine
