When Asus just forgets their customers, they themselves should try innovative methods:

I just modified the USB driver for TP-LINK TD-8811 modem for Asus AM602 (and Symphony SY602, They are the same and all have the same Broadcom chip), specially for Windows Vista/XP 64. I myself have tested this driver on Microsoft Windows XP SP3 32 and Microsoft Windows Vista Ultimate 64 SP1, AND EVERYTHING IS FINE.

I also found an updated firmware in http://www.asus.ru/ftp/spk/adsl/ .it also works fine for me but SNMP menu is lost! Some people may care about it, so use it on your own risk.

WOOWW ! 1300 downloads! COOL.
Also Port Forwarding for the Asus AM602:

I think the same procedure could do the trick for emule.

Recently in Asus download page http://support.asus.com/download/download.aspx?SLanguage=en-us 
in Broadband/xDSL/ section you can find AM602 again! but in OS selection screen there is no option (15 March 2009)!
