These are my notes on how to reduce memory consumption of debian on an HP t5135 thin client.
Add to modules blacklist:
blacklist snd_via82xx blacklist snd_ac97_codec blacklist snd_pcm blacklist snd_timer blacklist snd_mpu401_uart blacklist snd_rawmidi blacklist snd_seq_device blacklist via82cxxx_audio blacklist uart401 blacklist parport_pc blacklist parport blacklist pcspkr blacklist soundcore blacklist sound blacklist via82cxxx_audio
Remove device mapper from init scripts:
update-rc.d -f libdevmapper1.02 remove
Edit /etc/default/acpid:
MODULES="processor button thermal"
