 Okay, you're going to love this.  I bought a serial cable today, set
 it up, and voila, we've found a new quirk.  If I boot the image you've
 provided via a serial console, it works fine, there's no panic, it gets
 to sysinst (more on that below).  But if I boot using the framebuffer,
 the panic occurs.
 
 So, here's the full dmesg as I get from booting via a serial console:

 At which point the machine froze and did not accept console input.
 I had to yank the power cord to reset it.
 
 Now, back to the serial console session...  It does indeed recognize the
 OpenBSD partitions, like so:
 
 We now have your BSD-disklabel partitions as:
 This is your last chance to change them.
 
     Start  MB   End  MB  Size  MB FS type    Newfs Mount Mount point
     --------- --------- --------- ---------- ----- ----- -----------
 a:         1       799       799 FFSv1            Yes
 b:       800      1823      1024 swap
 c:         0      8677      8678 Whole disk
 d:      1824      8677      6853 FFSv1            Yes
 e:         0         0         0 unused
 f: Show all unused partitions
 g: Change input units (sectors/cylinders/MB)
 >x: Partition sizes ok
 
 d_ntracks   =10
 d_nsectors  =211
 d_secsize   =512
 d_secpercyl =2110
 d_secperunit=17773524
 dlsize      =17773524
 
 I proceeded to alter the partition sizes in sysinst, and continued.  It
 was successful.  I followed sysinst to the point where it asks for the
 location of the install sets.  (Since there weren't any available via
 the releng builds right now, I aborted.)
