Full ACK.
I made a short speed test with a hacked autoload function. I added a
condition that checks if the classname starts with ux_ and if so if it is
registered in $GLOBALS['TYPO3_CONF_VARS']['BE']['XCLASS'] or in FE xclasses
If that is not the case further autoloading will be skipped.

results for siege requesting cached pages:
trunk: 220 req/sec
hacked: 240 req/sec

I see some optmizing potential here ;-)

btw: in the same scenario TYPO3 4.2.7 delivers 287 req/sec
