[SCSI] SCSI block devices larger then 2TB

Greetings!

Current aic79xxx driver doesn't see SCSI devices larger, then 2TB. It fails with READ CAPACITY(16) command. As far as I can understand, we already have LBD support in kernel for some time now. So it's only the drivers, that need to be fixed? LSI driver is the only one I found working with devices over 2TB; I couldn't test any other driver, as I don't have the hardware. Is it really so bad, that only LSI chipset and maybe few others are capable of seeng such devices?

My kernel output with aic79xxx follows:
