 6.3 CD had the same problem as well, last I tried.  Also DL'd the 8.0
 livefs CD from the 200807 directory (8.0-CURRENT-200807-i386-livefs.iso)
 and it also had the same problem.  The latest Linux kernel (that I
 tried) also has a very very similar problem (I think it was 2.6.18).  So
 it's not something that isn't common throughout the open source OS world.
 
 
 On a related note...
 
 I have made the following additional observation and am attempting to 
 prove or disprove whether this is responsible.  The ACPI tables list IRQ 
 9 as being level triggered HIGH, whereas the "no APIC" boot log shows 
 IRQ 9 as being level triggered LOW (assigned by 'atpic').  I do not know 
 whether this is a problem in the ACPI table or the interpreter, but I 
 shall investigate this one further.  IRQ 9 (as I recall) affects 
 everything with a higher IRQ number on ISA platforms since if feeds from 
 the 2nd PIC.  So if keyboard and serial work ok, but the disk drives do 
 not, that might explain why.
