Loadlin? Citrix under linux? sys req for org vorbis?

Howdy. I have 3 mostly software questions.

0. What is the general impression of loadlin? From what I have read on
google it seems to be a good program, but I wanted to make sure that
this is the best option for loading linux using the windows bootloader.
And no lilo and grub are not an option, I tried.

1. Does the citrix client under linux suck? If so how much? (no, vnc,
and ssh are not options)

2. What are the sys reqs of playing org vorbis? Should I bother figuring
out how to get sound working on a pentium 100, or is that just too slow
play org vorbis at ~192 Kb/sec? I know that under windows on the same
machine that mp3's will play just fine, but org vorbis just sucks.
