The company that created Virtual PC, Connectix, was acquired by Microsoft in February early this year and indeed supported the product right up to August 15. A few weeks ago Microsoft released a new update of the product: "Virtual PC for Mac Version 6.1".
MacCentral reports that while Microsoft says the problem will be sorted out with the next version of Virtual PC — it has set no date for this. Meanwhile, customers who spent money on Virtual PC, then upgraded to the PowerMacG5 have to just lump it — and wait.

Virtual PC for Mac Is Not Compatible with the Apple Power Mac G5 Processor (Microsoft Knowledge Base Article - 827904)
Microsoft wrote:Because the Macintosh G5 processor does not support pseudo little-endian mode, Microsoft is rewriting and carefully testing portions of Virtual PC for Mac. Microsoft expects to deliver G5 compatibility in the next full version of Virtual PC for Mac. Microsoft will announce the timing of that release later.
As for Virtual PC for Mac 6.1, I don't see any point to update it.
- Changes from Virtual PC for Mac version 6.1
- Re-branding changes were made to both the Virtual PC application and the Virtual PC Additions to reflect the transition of Virtual PC from a Connectix-branded product to a Microsoft-branded product.
- Fixed an incompatibility problem between Virtual PC and the Apple Airport Extreme card. (Fixed in Virtual PC for Mac Version 6.0.2.)
- Fixed an issue that prevented users from properly drawing arcs in Java version 1.4.1.
- Added an AppleScript to enable a slower "compatibility mode" for installing software applications in a guest operating system that rely on copy-protected files or self-modifying code. Do not enable this setting unless you are having problems installing a particular piece of software. If this is the case, you can turn on the Compatibility Mode for the software installation and then turn it off once the installation has finished. Note that this mode causes the guest operating system and Virtual PC to run much slower, but it might allow greater compatibility for installing some applications.
- Fixed an issue involving auto-restore of PCs under Mac OS 9.2.2.
