Alan = kernel, Andre = IDE.  2.2.18 (kernel) + ide.2.2.18.1221 (IDE
patch) + 2.2.19pre8 (kernel patch).  See samples below.

Ensoniq AudioPCI (ES1370) was problematic if I tried to assign IRQ5 on
the KA7 (hard trailess lockups, all IRQ's migrated to 10 or 11
regardless of config, digital audio ScreamOfAgony), whereas IRQ 3 worked
fine.  Similar experiements with Intel chipset boards P3B-F & BP6 suffer
no such issues so I assume it's VT82C686/ES1370 specific.

Abit KA7, 2.2.19pre8 + ide.2.2.18.1221
