We won't.

Theoretically, you could continue to use that old custom-built version, with
no upgrading. But I'm not sure for how long you'll be able to compile it on a
system with modern libraries.
However, after I started a thread about this a week ago, I learned that there
are the following alternatives (in no particular order):
* upgrade your hardware
but be VERY CAREFUL to pick the processor correctly; test it for vmx flag using
LiveCD before buying (cat /proc/cpuinfo | grep vmx)
* use VirtualBox-OSE
but be aware that "Open Source Edition" means "crippled", ie. no USB support
for the guest
* use VirtualBox
but be aware that it is partly closed source
* use VMWare
but be aware that it is completely closed source, and support for kernel
modules is not at its best (ie. sometimes kernel upgrades break things). OTOH
when it works, vmware has by far best support for guest hardware (USB,
bluetooth, webcam, this, that...) in contrast to virtualbox.
Pick what works best for you. There is no good open source solution.
I have vmware on a F10 box, virtualbox on F11 box, and atm I'm evaluating a
tradeoff between having good host kernel support (virtualbox) versus good guest
hardware support (vmware). Other than that, they are pretty much equivalent in
features and performance.
HTH, :-)
