+What:   PRISM54
+When:   2.6.34
+
+Why:    prism54 FullMAC PCI / Cardbus devices used to be supported only by the
+        prism54 wireless driver. After Intersil stopped selling these
+        devices in preference for the newer more flexible SoftMAC devices
+        a SoftMAC device driver was required and prism54 did not support
+        them. The p54pci driver now exists and has been present in the kernel for
+        a while. This driver supports both SoftMAC devices and FullMAC devices.
+        The main difference between these devices was the amount of memory which
+        could be used for the firmware. The SoftMAC devices support a smaller
+        amount of memory. Because of this the SoftMAC firmware fits into FullMAC
+        devices's memory. p54pci supports not only PCI / Cardbus but also USB
+        and SPI. Since p54pci supports all devices prism54 supports
+        you will have a conflict. I'm not quite sure how distributions are
+        handling this conflict right now. prism54 was kept around due to
+        claims users may experience issues when using the SoftMAC driver.
+        Time has passed users have not reported issues. If you use prism54
+        and for whatever reason you cannot use p54pci please let us know!
