I'm not sure what alarm sound you mean... All sounds are in /home/QtPalmtop/sounds/, which are symlinks to /usr/QtPalmtop.rom/sounds/, and I didn't change any. If you can figure out which sound file it is that's annoying to you, tell me and I'll try to find a better one and use that next release.
VNC server should work (as long as it's a version reported to work on the 5600 in general). The kernel is identical to the Sharp ROM's, except with the Cache bug turned off (increasing speed). I haven't personally tried though, as I don't use VNC.
1.4 (changed from 1.3 to 1.4 -- I'm going to go to the more standard 1.x, where if x is an odd number it's development version, if even it's stable) should be up later this evening. I'm just too lazy to post it up now (it works well though ). The IPK feed will be slightly updated too, with Zautrix's NeIC in there, as opposed to ziciz for an IRC program. It's also been slightly hacked to give compatibility with ~ and & as IRC user prefixes (the source will be available).
So, I'll add a post when I do put 1.4 up. That'll be in a few hours (probably).
