Interestingly enough, even though AE states there is no compression, a co-worker opened the exported .avi file with VLC Media Player and it says that there IS a codec: RV24: Raw RGB 24-bit file
When opening the same .avi within quicktime (on my PC) it states that the codec is: WRAW, 256 colors
After Effects still says "no compression".
My original settings were: Microsoft AVI with "none" selected as the codec. If i select "uncompressed microsoft avi" I am forced to choose between V210 (which i believe is 10 bit) and UYVY (which is 8 bit I believe). Either way this involves using a codec and is NOT truely uncompressed.
I would use .mov's, but Fusion (our compositing software of choice) absolutely will not work with them, especially on our 64-bit machines (PC quicktime is still only 32 bit). When i export as a QT and select "none" as compression - AE reads it as "none" (not "no compression") and QT inspector reads it as "none" also. Very straightforward - "none" means no compression (like it should).
I seem to have opened a can of gummy worms along the way and now i am very confused about what really is an "uncompressed" format and very frustrated that CS4 PPro between Mac and PC are not very compatable.

AVI is a Microsoft format and it is not native to Apple systems. Maybe you can find a AVI plugin for your MAC?
Just google AVI for MAC
Premiere's support for Uncompressed media usually includes third-party hardware, like that from AJA or BlackMagic.
I'd ask why you're bringing the exported file into Premiere on the Mac? Just use the export with Fusion as you desire.
