[ale] Disk access is realllllly slowwwww

[Dow Hurst]

The latest 2.4 kernel contains a patch that may fix your problem.  Seems 
there is new IDE hardware out or a IDE chipset that isn't understood by 
any kernel less than 2.4.21-rc4 (as of yesterday) and so the drive 
reverts to no DMA access.  I had problems with a Dell Inspiron 8500 and 
found out about this new hardware that requires a patch.  Emperor Linux 
has a robust patch they have contributed to the kernel guys.  The latest 
2.4 kernel may have this patch but I've heard that any but the latest 
was broken.
