X-Chat in extras-devel works fine.

Some problems I have had with it, along with the workarounds to make things very usable for me:

- Settings are not saved, and attempting to save settings crashes XChat
-- Workaround: Edit the config file: ~/.xchat2/xchat.conf

- No tab key for autocompletion of users' names
-- Workaround: remap my keys to use Fn+Rightarrow as Tab key

- Upon closing, the maemo-xinput-sounds process sometimes runs away and starts consuming 97% of the processor until the battery dies
-- Workaround: "killall maemo-xinput-sounds" if the load applet shows strange activity after closing XChat.
