+ISDN diversion services support

+  This option allows you to use some supplementary diversion

+Math emulation support
+CONFIG_M68KFPU_EMU
+  At some point in the future, this will cause floating-point math
+  instructions to be emulated by the kernel on machines that lack a
+  floating-point math coprocessor.  Thrill-seekers and chronically
+  sleep-deprived psychotic hacker types can say Y now, everyone else
+  should probably wait a while.
+
+Math emulation only kernel
+CONFIG_M68KFPU_EMU_ONLY
+  This option prevents any floating-point instructions from being
+  compiled into the kernel, thereby the kernel doesn't save any
+  floating point context anymore during task switches, so this
+  kernel will only be usable on machines without a floating-point
+  math coprocessor. This makes the kernel a bit faster as no tests
+  needs to be executed whether a floating-point instruction in the
+  kernel should be executed or not.
+
+Math emulation extra precision
+CONFIG_M68KFPU_EMU_EXTRAPREC
+  The fpu uses normally a few bit more during calculations for
+  correct rounding, the emulator can (often) do the same but this
+  extra calculation can cost quite some time, so you can disable
+  it here. The emulator will then "only" calculate with a 64 bit
+  mantissa and round slightly incorrect, what is more then enough
+  for normal usage.

+  This driver is for USB parallel port adapters that use the 
+  Lucent Technologies USS-720 chip.
+  
+  The chip has two modes: automatic mode and manual mode.
+  In automatic mode, it looks like a standard USB printer. Only
+  Printers may be connected to the USS-720 in this mode.
+  The generic USB printer driver (CONFIG_USB_PRINTER, above)
+  may be used in that mode.
+
+  Manual mode is not limited to printers, any parallel port
+  device should work. This driver utilizes manual mode.
+  Note however that some operations are three orders of a magnitude
+  slower than on a PCI/ISA Parallel Port, so timing critical

+Kernel httpd acceleration (expirimental)
+CONFIG_KHTTPD
+  The kernel httpd acceleration daemon (kHTTPd) is a (limited) 
+  webserver build into the kernel. It is limited since it can only

+  kHTTPd module; this is NOT enough to have a working kHTTPd. 
+  For safety reasons, the module has to be activated by doing a
+  "echo 1 > /proc/sys/net/khttpd/start" after inserting the module.

+  Before using this, read the README in /usr/src/linux/net/khttpd !

+  The kHTTPd is expirimental. Be careful when using it on a production
+  machine. Also note that kHTTPd doesn't support virtual servers yet.
