Linux -> BSD drive addresses

Hi all--

I recently switched from Linux to FreeBSD, and am
puzzled by FreeBSD's drive addressing scheme. Basically I have a Linux
partition on my second drive that contains all of my mp3s. It is the
second partition on the disk. Here's what fdisk reports:

  wintermute# fdisk /dev/ad0
  ******* Working on device /dev/ad0 *******
  parameters extracted from in-core disklabel are:
  cylinders=2658 heads=240 sectors/track=63 (15120 blks/cyl)

  Figures below won't work with BIOS for partitions not in cyl 1
  parameters to be used for BIOS calculations are:
  cylinders=2658 heads=240 sectors/track=63 (15120 blks/cyl)

  Media sector size is 512
  Warning: BIOS sector numbering starts with sector 1
  Information from DOS bootblock is:
  The data for partition 1 is:
  sysid 12,(DOS or Windows 95 with 32 bit FAT, LBA)
      start 257040, size 20487600 (10003 Meg), flag 0
  	  beg: cyl 17/ head 0/ sector 1;
  	  end: cyl 1023/ head 239/ sector 63
  The data for partition 2 is:
  sysid 131,(Linux filesystem)
      start 20744640, size 19444320 (9494 Meg), flag 0
  	  beg: cyl 1023/ head 255/ sector 63;
  	  end: cyl 1023/ head 239/ sector 63
  The data for partition 3 is:
