I'm looking for a distro to fit the following situation:

Purpose - Wireless AP
Hardware - Ancient P166, 32MB RAM, 2GB partition available, no CD-ROM, 3Com wired NIC, Atheros-based wireless NIC.
Install method - bootstrap from existing Linux install over ssh, preferably with no physical interaction with the machine.

The existing install is Pebble Linux, a Debian derivative, and it's in a 1GB partition on the same hard drive as the free 2GB. Pebble is actually doing the AP job at the moment, but it's running a 2.4.26 kernel, and I'd really like to start from scratch with a recent 2.6 kernel, udev, etc. If the hardware wasn't so crappy, I'd use Arch Linux (my favourite distro), but it's for i686 only. So I've gone ahead and used debootstrap to install Debian Sarge alongside Pebble, but only because it was the only distro I knew of that could be installed that way. The intention is to do a minimal install - no X, etc, so I want to avoid downloading CDs full of unnecessary apps. debootstrap (and the Arch equivalent) install a base system over the net, and I'd be interested to hear of any other distros that can do that.

All ideas appreciated. TIA.
