"Currently the only way to run mods is by creating another qlaunch file. Copy qlaunch.gpe to a new file and change it's name. Read the instructions for running the mod and add the command line parameters to the end of /mnt/sd/quake/quake.gpe. Eg, if the instructions say to type 'quake -game somemod +map somemap' then your launcher file should contain '/mnt/sd/quake/quake.gpe -game somemod +map somemap'. Not all mods will work, and without a serial cable it sometimes won't be clear what the problem is."
