SiI0680 ATA RAID question

[Dmitry Pryanishnikov]

Hello!

  In 5.3-RELEASE ERRATA I see the following:

    (1 Nov 2004) ATA RAID support for the CMD649 and SiI0680 ATA
    controllers is non-functional in this release. When such a controller
    is brough up under ata(4) (ataraid) on 5.3, the RAID configuration
    stored under 5.2 or prior may be corrupted.

What's the reason of the problem with SiI0680: inferiority of the hardware or 
just programming error? Is this problem fixed in 6-CURRENT? If so, will this 
fix be merged to 5-STABLE?

Sincerely, Dmitry
