Now the company has announced that Mandrakelinux 10.1 Official now supports the extended 64-bit architectures embodied in the latest Intel Xeon chips as well as the AMD Opteron processors. The x86-64 release, like the Xeon-64 and Opteron processors, can support legacy 32-bit code.
The updated software also supports the NX (no execute) security features of the Xeon processors through a feature Mandrakesoft calls Enhanced Virus Protection. Mandrakelinux 10.1 for x86-64 is based on the PowerPack implementation of its 32-bit Linux; and costs E119, compared to E79.90 for the PowerPack edition.
So if you want 64-bit support with your Linux, Mandrakesoft is charging a slight premium.
