Hello World,
This little patch enables the workaround for the ISA DMA bug on ALi15x3
chipsets with the PCI-ISA bridge. The patch was originally written by
Angelo Di Filippo <adifilip@ubiquity.it> for Kernel 2.3.45. I adapted it to
Kernel 2.4.1.
This chipset can be found in many laptops of the Acer Extensa series, and
the bug prevents the sound chip (an OPL3/SA2) from working.

The patch is also attached in case my mailtool kills the format (I don't
hope it does)
