Hope this is the right forum and someone is interested and perhaps this isn't covered anywhere else?
I was always a bit annoyed about the XOOPS-internal debugging especially when working with (x)ajax. This gives you always (mostly) problems.
So I ended up using FireBug + FirePHP as addons for Firefox. I rewrote class/logger/render.php to output the debug to FirePHP. With this solution you are highly flexible.
As a module developer you can write any kind of debug notice you want without destroying the layout with echos or even writing to a logfile.
Example:
le="color: #000000"><?php $fb->log($thevariwanttodisplay);
Of course you could adapt render.php to your needs like displaying server vars etc.
You can get FirePHP
HEREAnd here is the code for class/logger/render.php (hope the textsanitizer won't mess up):

Output is still looking a bit ugly, but better than before.
Hope this is helpful to someone?
edit: added the query for xoopsUser in order to hide the debug for guests
