devb-eide & Intel chipsets 845E witch ICH4

I have motheboard MSI 845E Max (MS-6566E) with Intel chipset 845E + ICH4 and HDD Seagate IV 80GB.

Support devb-eide driver DMA mode for Intel chipset ICH4?
Measured transfer speed:
cp -V /dev/hd0 /dev/null

2704 kb/s and 99% CPU load — PIO mode

For motheboard with Intel chipset ICH2 devb-eide working in DMA mode OK

21304 kb/s and 33% CPU load — DMA mode

devb-eide only supports PIO mode on the ICH4 chipset. We are in the process
of adding ICH4 support.

Will ICH4 support make it into the next release? There are a lot of machines out there
now with this chipset.
