AmigaOne graphics card help please...

[EDS.bod]

I've just bought (or rather, ordered) an AmigaOneG3-SE from Eyetech and I'd like to ask if anyone knows a graphics card that can be used with both LinuxPPC and AmigaOS4.0?  I've been offered a 64mb Voodoo 4500 card for £30 - would this do?  Will it make a difference if the card is AGP or PCI?
Also, can someone point me to a good Linux site for novices?

Thanks in advance.

O.k.,  Looks like I might go for the Voodoo 4500 for now and upgrade later but what I really want to know, now that the compatibility with the A1 and OS4.0 is sorted out, is will the Voodoo work with LinuxPPC?
