I built a NetBSD 6.0_BETA2/i386 .iso from June 13 sources, and it booted
and worked on an IBM x335 box just fine...

mickey# disklabel cd0
# /dev/rcd0d:
type: ATAPI
disk: optical media
label: fictitious
flags: removable
bytes/sector: 2048
sectors/track: 100
tracks/cylinder: 1
sectors/cylinder: 100
cylinders: 3599
total sectors: 359847
rpm: 300
interleave: 1
trackskew: 0
cylinderskew: 0
headswitch: 0           # microseconds
track-to-track seek: 0  # microseconds
drivedata: 0 

4 partitions:
#        size    offset     fstype [fsize bsize cpg/sgs]
 a:    359847         0    ISO9660       0             # (Cyl.      0
-   3598*) 
d:    359847         0        UDF                     #
(Cyl.      0 -   3598*) disklabel: boot block size 0
disklabel: super block size 0
disklabel: partitions a and d overlap

Later...
