Greetings,

I'm writing a streams device driver for 386 UNIX SVR4 and I need 512
bytes of DMAable memory that is aligned to a 512 byte boundary (i.e.
the starting address is a multiple of 512).  How is this done ?  None
of the kernel memory allocators take an alignment argument.  Please
send all responses via e-mail and I will post a summary if I get
enough useful information.  Thanks.
