mas v jadre podporu pre tento ide chipset???
grep CONFIG_BLK_DEV_ALI15X3 /boot/config-`uname -r`

CONFIG_BLK_DEV_ALI15X3:
This driver ensures (U)DMA support for ALI 1533, 1543 and 1543C
onboard chipsets.  It also tests for Simplex mode and enables
normal dual channel support.
If you say Y here, you also need to say Y to "Use DMA by default
when available", above.  Please read the comments at the top of
drivers/ide/pci/alim15x3.c.
If unsure, say N.
