Just wanted to confirm Debian Lenny works 100% on Dell Mini 10v after a lot of tweaking.
For anyone who wants to do it, I installed Debian Lenny 5.0.2 using an external burner. From there I downloaded the NIC driver (RTL8101E) using a second computer and dumped it on the mini 10v. You will have to apt-get some packages off of the Lenny CD to be able to install the NIC.
After the NIC is installed, you can download and install the broadcom wireless drivers for wifi.
Last but not least, ALSA needs to be upgraded to the latest version (.20 as of today) for sound to work (internal mic will work as well)). This was a bit of a pain but basically you need to configure and make && make-install the latest alsa-drivers, alsa-lib, and alsa-util
Took me a few days to hammer down this process but I have my 10v sitting next to me on a fully functional Lenny desktop
