You can just wire drives directly to IDC26, but that does require caution in proper wiring as those I/O pins are highly sensitive.

Actually I found a mistake in my grub command line. Now my histogram is better, in that there are only a few excursions to debug now.

It looks like only interrupt that seems to fire at roughly the same frequency is IRQ 20 which is described as

IO-APIC 20-fasteoi pata_pdc2027x[0000:03.05.0]

It is interesting that it fires on CPU1. I thought I had a command in my grub setup to disable hyperthreading.
