Yes, but how do I use such a patch? (I have not much Linux experience
yet.)

Easier? It looks much more complicated to me. What I want to say: I have
no idea how to realize that solution. For example currently I use kernel
2.4.10 for pentium on Suse 7.3. I don't know if I have to expect any
problems using the givven 2.4.17 kernel for 386. Also I don't know what
APM is and if I need it or not. And this are not the only points I do
not understand, so therefore I am asking here for an advise.

Both, ADDR_DATE and RTC_DATE? Doesn't it interfere with each other,
because of the following points:
- for ADDR_DATE (0x51) there has to be SHIFT_DATE 3 and RESET_DATE OFF,
  but for RTC_DATE (0x70) it should be SHIFT_DATE 0 and RESET_DATE ON.
  Or does SHIFT_DATE only affect the ADDR_DATE and RESET_DATE only
  RTC_DATE?
- 0x70 should be C0 if ADDR_STAT is set to off or ADDR_STAT is set to
  every day. (I think the latter is never be used by nvram-wakeup?)

I did not use guess, but I can mail some xxd /dev/nvram outputs - I
write here at the end of this message an excerpt:
