Tweak compcache configuration for the brave and customizers (not recommended if you don't know what this means):
if you want to change the ramzswap size I guess you know what you are doing and brave enough to edit /system/init.d/ramzswap.sh and change the disksize_kb value by yourself.
As far as I have tested, 80MB and 92MB yield very good performance and I suspect using bigger Ramzswap may decrease performance because there is more RAM to compress/decompress and also more memory to free via swap notify (to avoid excessive fragmentation). To sum it up, I don't think we need 400MB of RAM on a phone.
If you notice more lag/stuttering, please revert to the 80MB or 92MB configuration.

For kernel developers who want to compile their own kernel:
The kernel is obtained by applying Compache 0.5.4 swap notify callback patch, ext4, a few other patches to HTC's Hero sources.
Then there is a tweaked config file to produce teknologist kernel.
And additional modules (compache for instance) to compile agains the kernel source tree.
For a compcache howto, have a look here.
All the source tree is hosted on github here.
As always the config file for the kernel you installed is available on your device as /proc/config.gz
