<DIV><SPAN class=018474115-26072007><FONT face=Arial size=2>The System clock
speed of the Acadia may be changing yet again. In order to find a better way of
detecting the correct system clock speed, this method was devised. It measures
the system clock speed against the performance timer in the CPLD the first time
that the function is called and chooses the correct system clock speed. It then
saves the result in the global variables to use for each future call to the
function. </FONT></SPAN></DIV>

<DIV><SPAN class=018474115-26072007><FONT face=Arial size=2>I also added the
environmental variable, "sysclk," set in the misc_init_r function so that
it could be passed to Linux. (I do not know if Linux takes this argument, so I
am not sure if it is useful.)</FONT></SPAN></DIV>

are any problem with this approach, but it seems to be a better solution to the
