On Ubuntu 7.04, you have to use /dev/sda rather than /dev/hda, but when you do this it generates some warnings:
root@T40-thinkpad:/home/user# hdparm -d1c1u1m16 /dev/sda /dev/sda: setting 32-bit IO_support flag to 1 HDIO_SET_32BIT failed: Invalid argument setting multcount to 16 HDIO_SET_MULTCOUNT failed: Inappropriate ioctl for device setting unmaskirq to 1 (on) HDIO_SET_UNMASKINTR failed: Inappropriate ioctl for device setting using_dma to 1 (on) HDIO_SET_DMA failed: Inappropriate ioctl for device HDIO_GET_MULTCOUNT failed: Inappropriate ioctl for device IO_support = 0 (default 16-bit) root@T40-thinkpad:/home/user#

I have the same experience on my R40, although I cannot set DMA mode with hdparm, the DVD still seems to work at a reasonable pace. This is with Ubuntu 7.10 (Gutsy).
