I think Debian is the best linux for using it with maya 6. I have experiece with maya on suse, redhat and debian sarge. And debian is the best (not the easiest) way . . . .
I use the rpm and convert it with
alien -c packetname.rpm
it will create .deb packages
then install them with
dpkg -i filename.deb
you need to install the packages
maya6-0_xxx.deb
awcommon_6.0xxxx.deb
maya will be installed in the folder /usr/aw
you project folders are under your home directory in folder maya/projects
I have made good experience with installing
openmotif_2.1.30xxx.deb
but this is not necessary
you must have installed a 3D graphic driver and openGL !!
here a link for installing maya under debian:
