More p5-590 firmware woes

In reference to my previous post about the long-awaited new p5-590 firmware, here's the latest IBM masterpiece from their website:

This package provides new firmware for i5, OpenPower, p5 Servers and IntelliStation 285, EXCEPT for the following systems: 9119-590 and 9119-595 and 9406-595.
Although 9119-590, 9119-595 and 9406-595 systems are being shipped from the factory with this level of code installed, field upgrades of these models to release level SF235_180 are not supported at this time. This restriction is limited to the 59x models. If you have questions regarding this, please contact your next level of support.

If I had purchasing power, I would have a serious talk with IBM sales people about this >:-(
