Hi, I have Acer Aspire 4520G (no 4520), but there is only 2 difference - I have 2GB Ram (but it doesn't matter) and there is GeForce 8400M G in my notebook.
In some of the day I'll try to install Leopard (probably Leo4allv4.1 or iAtkos v4a). Previously I successful installed Leopard on Toshiba L20 (L20-101) so I shouldn't have problems (as I think ;]).
What about WiFi (100% working?), card reader (Ricoh), Bluetooth (Broadcom), VGA output, S-Video output and finaly screen resolution (is 1280x800 working???)?
Sorry for my probably stupid questions, but I like know everything before I'm starting something .
Oh, and sorry for the English.
Please write again, for step by step how to install newest Leopard and update to 10.5.7 on Acer Aspire 4520 (4520G).
