This page contains a HOWTO of how the ARMv7 port of Funtoo Linux on the HP TouchPad is being created. This is a work in progress.
Initial Setup with Preware, F4, Xecutah
For those wanting to help, install Preware, the F4 kernel, and OpenSSH and Xecutah. Set up ssh access to your touchpad by using the xterm on TouchPad (launched via Xecutah) to copy a remote id_dsa.pub or id_rsa.pub public key file to the directory /var/home/root/.ssh/authorized_keys (ie. rename the file to authorized_keys. Use ifconfig in xterm to get your TouchPad's IP address, and you should now be able to "ssh" in.
