It shows UDMA/100 for HDD and UDMA/33 for DVD-ROM. Visual inspection 
confirms that this is correct - DVD-ROM has 40-pin cable and HDD has 
80-pin one. So at least the result is not wrong.

ata1: PATA max UDMA/100 cmd 0x000101f0 ctl 0x000103f6 bmdma 0x0001ffa0 irq 14
ata2: PATA max UDMA/100 cmd 0x00010170 ctl 0x00010376 bmdma 0x0001ffa8 irq 15
ata1.00: ATA-5: ST380021A, 3.19, max UDMA/100
ata1.00: configured for UDMA/100
ata2.00: ATAPI, max UDMA/33
ata2.00: configured for UDMA/33

Should the ATAPI line contain UDMA/100 if 40-pin cable is present??
