Upgrade to Hardy Kubuntu 
* enable port tcp 80 forwarding on your firewall

because adept_manager connects directly to http://changelogs.ubuntu.com/
https://bugs.launchpad.net/ubuntu/+source/adept/+bug/153016/comments/13

* kdesu "adept_manager --dist-upgrade-devel"

if you use a proxy like approx stop adept_manager after changing /etc/apt/sources.lists and rewrite to

deb http://proxy:9999/ubuntu/ hardy-security universe main multiverse restricted
deb http://proxy:9999/ubuntu/ hardy-updates universe main multiverse restricted
deb http://proxy:9999/ubuntu/ hardy main universe multiverse restricted

and start it again.

after upgrade done add
deb http://proxy:9999/medibuntu hardy free non-free

to /etc/apt/sources.lists

on my proxy /etc/approx/approx.conf:
ubuntu          http://ubuntu.inode.at/ubuntu
medibuntu http://de.packages.medibuntu.org

apt-get install isdnutils-base

because ippp0 sets a default route we change to ippp1:

mv /etc/isdn/device.ippp0 /etc/isdn/device.ippp1
mv /etc/isdn/ipppd.ippp0 /etc/isdn/ipppd.ippp1

/etc/isdn/device.ippp1 (remove '# REMOVE'):
LOCALMSN='XXXXX'

Using a Flashdisk and take care about limited writes 
For me it is sufficient to have data written every 20 Minutes.

To enable this i use laptop-mode and set some values in /etc/sysctrl.conf:

vm.swappiness = 0
vm.laptop_mode = 1200
vm.dirty_writeback_centisecs = 120000
vm.dirty_expire_centisecs = 120000
vm.dirty_ratio = 40
vm.dirty_background_ratio = 1
