IMHO this request was much too non-verbose (both Subject *and* introduction). Interested parties wouldn't even know that they should be interested in it ;)

What further steps should now be taken for this patch to be included in a sufficiently official kernel in some form?
I'm asking now since as some kind of weird Christmas present this one has found its way under my desk rather very accidentally:
00:00.0 Host bridge: Intel Corporation 440LX/EX - 82443LX/EX Host bridge (rev 0 3) 00:01.0 PCI bridge: Intel Corporation 440LX/EX - 82443LX/EX AGP bridge (rev 03) 00:04.0 ISA bridge: Intel Corporation 82371AB PIIX4 ISA (rev 01) 00:04.1 IDE interface: Intel Corporation 82371AB PIIX4 IDE (rev 01) 00:04.2 USB Controller: Intel Corporation 82371AB PIIX4 USB (rev 01) 00:04.3 Bridge: Intel Corporation 82371AB PIIX4 ACPI (rev 01) 00:06.0 SCSI storage controller: Adaptec AIC-7880U 00:0a.0 Ethernet controller: 3Com Corporation 3c905C-TX [Fast Etherlink] (rev 7 4) 00:0c.0 VGA compatible controller: ATI Technologies Inc 264VT4 [Mach64 VT4] (re v 3a)
So this means I have ICH5, PIIX4M and PIIX4 rev. 01 (most likely buggy) and some non-Intel chipsets. Ideal conditions for testing.
