Sounds similar to my specs. except that we have 32 T5135's.  Today the 
system appears to have worked fine today for us.

Things that seem to help:
-ltsp-build-client --with-sourceslist . Then
chroot /opt/ltsp/i386
apt-get update
apt-get upgrade

-the settings mentioned for the /etc/firefox-3.0/pref/firefox.js file. 	
http://k2.mtacademy.us:8081/tmp/firefox.js
	pref("extensions.update.enabled", true);
	pref("intl.locale.matchOS", true);
	pref("browser.shell.checkDefaultBrowser", false);
	pref("browser.EULA.override", true);
	pref("browser.safebrowsing.enabled",false);
	pref("browser.safebrowsing.malware.enabled",false);
	pref("browser.urlbar.maxRichResults",false);
	pref("browser.cache.offline.enable",false);
	pref("browser.cache.disk.enable",false);
-I noticed the  /home/user/.xsession-errors file was complaining about 
not finding the video driver so I install xorg-driver-fglrx on the 
server.  Not sure if the 5530's have the same video.
-My lts.conf file is: (http://k2.mtacademy.us:8081/tmp/lts.conf)
	[default]
		LDM_DIRECTX=True
     		SOUND=Ture
     		LOCALDEV=True
     		SYSLOG=server
     		USE_LOCAL_SWAP=True
     		X_COLOR_DEPTH=16
		#X_MODE_0=1024X786
     		LDM_PASSWORD=xxxxxx
     		LDM_LIMIT_ONE_SESSION=True
	[00:1e:0b:39:a3:40]
		LDM_AUTOLOGIN=true
		LDM_USERNAME=guest2039
	[00:1e:0b:39:9e:4c]
		LDM_AUTOLOGIN=true
		LDM_USERNAME=guest2038
	[00:1e:0b:39:9d:19]
		LDM_AUTOLOGIN=true
		LDM_USERNAME=guest2037
-You may want to disable the daemon server for tftpd-hpa as it is 
enabled in inetd.conf
-adding to /etc/host.allow
nbdswapd: ALL: keepalive




Anybody looking for a kiosk type of setup?  The following file may help 
you out: /etc/X11/Xsession.d/10KioskCleanUp
http://k2.mtacademy.us:8081/tmp/10KioskCleanUp

if [ `stat -c %G $HOME` == guest ]; then
     for goodbye in `ls -A $HOME/.`
	do if [ ! -e "/home/doNotDelete/$goodbye" ]; then
     	    rm -fR "$HOME/$goodbye"
	fi
     done
     chmod 700 $HOME
     cp -r /etc/skel/* $HOME
     cp -r /etc/skel/.[a-z]* $HOME
     chown -R "$USER:guest" $HOME
fi
Basically, anybody a member of guest gets their directory blown away on 
login.
