For Windows XP?, Not that I know of. There are proprietary versions
for Vista and I believe Professor Ripley is working on an experimental
version for the 64 bit versions of Windows.
We're planning to release 64 bit builds with R 2.11.0. They are
currently being built as part of the test process, though the builds are
still a little irregular.

The 64 bit versions of R will require a 64 bit version of Windows to run
on. I think there may be 64 bit versions of XP, but they are uncommon
and I don't know if they support our builds; we're testing in 64 bit
Vista and Windows 7.
Actually, the 64-bit version that you can currently download is a daily
build on Windows Server 2008 (where all the package checks happen as well).

Revolution Computing also sells a build produced with a different
compiler. It has the advantage that the compiler is probably in better
shape than the one we are using and they'll provide support with it; the
disadvantage is that they'll charge for it, and they are probably not as
up to date as us with respect to released version number.

Your sizes function is useful thanks - but is there some R parameter to
allow maximum usage of memory?
Read the Windows FAQ and seearch on "memory".
