weird characters installing netscape 7

[Gianluca Cecchi]

I have some Dell 5324 network switches.
To manage them via web, with firefox or epiphany I get the message
"The following browsers are supported :
Microsoft Internet explorer 5.5 and above
Netscape Version 7.1 and above
"
I  downloaded netscape 7.2 full installer and tried to install it, but
I get weird characters in the first window and other ones....
Instead of characters in text and buttons, I get only small rectangles...
This is on fc5 x86_64, while the installer is an x86 binary; I don't
know if it can make any  difference
in README file there is for requirements:
      * glibc - 2.2.4
      * gtk+ - 1.2.0 (1.2.5 or later preferred)
      * XFree86-3.3.6
      * Glib 1.2.x
so it is quite old (infact netscape 8 is available only for Windows)
doing ldd of the installer bin I get:
[gcecchi at pevit00 netscape-installer]$ ldd ./netscape-installer-bin
         (0xffffe000)
        libgtk-1.2.so.0 => /usr/lib/libgtk-1.2.so.0 (0xf7e33000)

        libXdmcp.so.6 => /usr/lib/libXdmcp.so.6 (0x00df2000)
while
file ./netscape-installer-bin
./netscape-installer-bin: ELF 32-bit LSB executable, Intel 80386,
version 1 (SYSV), for GNU/Linux 2.2.5, dynamically linked (uses shared
libs), for GNU/Linux 2.2.5, stripped

Any hint how to work around with installation or to trick the dell
switch to let it think I have netscape...?
Any hint on how to use wine eventually in a x86_64 fc5 system?
Thanks in advance
