Interesting discovery about HelenOS/sparc64

In the newly released HelenOS 0.4.0, we deliver improved support for 64-bit SPARC machines. This improved support is not so much interesting because of the higher number of peripherals supported (even though that number has also gone up), but mainly because of the higher number of individual SPARC processor models on which HelenOS can run. When I go through the processor list on this page, and count the UltraSPARC T1 processor, which we will soon officially cover too, I inevitably come to the conclusion that HelenOS has the best support for SPARC V9 processors, right after Solaris, OpenBSD and Linux.
