I know such message may be a bit noise to gurus on this list, but as a
newbie I constantly find searching other people's old post might help,
so I just write done solution to all problems I have solved, hoping it
can help the next newbie lurking on this list or coming to this list by
googling around.

I. [solved] keyboard doesn't work: solved, need to adjust keymap
(thank you for suggested this);
II. [solved] not able to access /dev/hda, probably new kernel
does not recognise on-board IDE controller. Related kernel
parameter I configured are:
I. CONFIG_SUN_PARTITION: y
II. CONFIG_BLK_DEV_SIIMAGE: y
==> solution is to activate CONFIG_BLK_DEV_CMD64X kernel option

III. [given up] parallel port stopped working, it behave
like /dev/null (swallow all input to it, no error message,
printer no response). /dev/lp0 is not mentioned in dmesg. I
remember on 2.4 kernel I use "PC-style Parallel Port" and it
works in ECP mode. Related kernel parameter I configured are:
I. CONFIG_PARPORT: y
II. CONFIG_PARPORT_PC: y
III. CONFIG_PARPORT_PC_FIFO: y
IV. CONFIG_PARPORT_1284: y
==> progress: after re-creating /dev/lp0 node it works a bit
better
dmesg | head -n 4 > /dev/lp0 would print something out
dmesg | head -n 40 > /dev/lp0 would hang the OS
my plan: next step is to text various parameter of parport

IV. [solved] USB Printer do not work. dmesg shows it detected
USB Printer but no device appear in /dev/usb. Related Kernel
Parameter:
I. CONFIG_USB_PRINTER: y
==> solution is to run this command as root:
# mknode /dev/usblp0 c 180 0
and set cups to use /dev/usblp0 for printer

V. [almost given up] all ALSA sound driver are enabled, dmesg
said Sun CS4231 is detected and use irq 10. Try to play mp3 file
using madplay, it hangs there after display song title, no sound
output, kill -TERM and kill -KILL cannot remove the dead
mplayer. Related kernel config:
I. CONFIG_SND: y
II. CONFIG_SND_SUN_CS4231: y
==> current progress: will try using different kernel following
suggestions on the list or try alsa-driver package
VI. [no clue yet] serial port doesn't work. I need serial port in
order to manage another headless server with this machine acting
as dumb terminal (using minicom).
dmesg shows no ttyS device. 'MAKEDEV update' can
create /dev/ttyS0 and /dev/ttys1 but accessing these
devices is not possible:
sappho zhangweiwu # cat /dev/ttyS1
cat: /dev/ttyS1: No such device or address
I have enabled following options in kernel:
sappho linux # grep -i serial .config
# CONFIG_SERIAL_NONSTANDARD is not set
# Non-8250 serial port support
CONFIG_SERIAL_SUNCORE=y
CONFIG_SERIAL_SUNZILOG=y
CONFIG_SERIAL_SUNSU=y
CONFIG_SERIAL_SUNSAB=m
CONFIG_SERIAL_SUNHV=y
CONFIG_SERIAL_CORE=y
CONFIG_SERIAL_JSM=y
