To play FL online you need to add overrides for DirectPlay in winecfg:
dplayx.dll
dpnet.dll
dpnhpast.dll
dpwsockx.dll
It will lag online, but it's playable.

Well, I'm a die-hard *nix fan, but... I dual-boot for FL - getting it to work under Wine would just not be worth the hassle, and having Windows available is sometimes useful. It's not really hard nor expensive to *cough* find a Windows XP installation CD and dual-boot. Otherwise, well, get used to some lag and fiddling whenever a new version of Wine comes out.
There's a few submissions on WineHQ's AppDB. Shows how to install / getting it up, you just need to use the actual version it was tested on.... it would yield better results.
